7 week pregnancy: Baby development, symptoms and Tips
Short Answer: At 7 week pregnancy, your baby is an embryo about 1 cm long, roughly the size of a blueberry, and weighs less than a gram. The heart beats at about 120 to 150 beats per minute and can be seen on a vaginal ultrasound in most pregnancies. The arms and legs are growing from small buds, the face is taking shape with nostrils and eye spots, the brain is growing fast and the umbilical cord and placenta are developing. Your body is making hCG at high levels, so nausea, tiredness, sore breasts, bloating and frequent urination are at their peak for many people, although some have few symptoms and that is normal too. This week, book your first prenatal visit and scan, take folic acid and iron as advised, avoid alcohol, tobacco and unapproved medicines, and learn the warning signs of ectopic pregnancy and miscarriage. Call a doctor for severe or one-sided pain, heavy bleeding, dizziness, fainting, shoulder-tip pain, fever or vomiting that stops you keeping fluids down.
Pregnancy weeks are counted from the first day of your last period, not from conception. Seven weeks pregnant means about five weeks since conception, and about three weeks after your missed period. You are in your second month, about one and three-quarter months pregnant, and your due date is about 33 weeks away. For the week before, read our guide to 6 weeks pregnant, and for the next week, 8 weeks pregnant. To follow the whole journey, see our pregnancy guidelines week by week.
Week 7 at a glance
| Detail | At 7 weeks |
|---|---|
| Trimester | First |
| Months | About 1.75, in the second month |
| Stage | Embryo |
| Baby’s length | About 1 cm (range 7 to 14 mm), crown to rump |
| Baby’s weight | Less than 1 gram |
| Size comparison | A blueberry |
| Weeks since conception | About 5 |
| Heart rate | About 120 to 150 beats per minute, rising |
| Weeks to go | About 33 |
Sizes are tiny and vary between guides and between pregnancies. Doctors measure the embryo from the top of the head to the bottom, called the crown-rump length, in millimetres. A difference of a millimetre or two from a chart is normal, and an early scan is the best way to date your pregnancy.
How many months is 7 weeks?
At 7 weeks, you are in the second month of pregnancy, about one and three-quarter months along. The old claim that 7 weeks is “the first month” is not right. Doctors count in weeks because months are uneven and weeks are exact.
| Weeks | Months | Trimester |
|---|---|---|
| 1 to 4 | Month 1 | First |
| 5 to 8 | Month 2 | First |
| 9 to 13 | Month 3 | First |
| 14 to 17 | Month 4 | Second |
| 18 to 22 | Month 5 | Second |
| 23 to 27 | Month 6 | Second |
| 28 to 31 | Month 7 | Third |
| 32 to 35 | Month 8 | Third |
| 36 to 40 | Month 9 | Third |
A full pregnancy lasts about 40 weeks counted from your last period, which is about nine months and one week. The count starts before conception, so at 7 weeks pregnant your baby has been growing for about five weeks.
Your baby at 7 weeks
This is a week of fast change. The embryo has doubled in size in a week and is building the structure of almost every organ, so food, folic acid and avoiding harmful substances matter a great deal.
Size and shape. The embryo is about 1 cm long and curled like a C, and its head is large compared with the body. It grows about a millimetre a day. By the end of week 8, it will be about 1.6 cm.
Heart. The heart is dividing into four chambers, and the valves and the vessels leaving it are forming. It beats at about 120 to 150 beats per minute at 7 weeks and rises to 150 to 170 by 9 weeks. A rate below about 100 at 6 weeks, or a bit slower than average early on, is often normal, and doctors judge it with the size of the embryo and a repeat scan. The heart is not fully formed until about 10 weeks.
Brain and nervous system. The brain has grown into five regions, and it is growing quickly, which is why the head looks so big. Nerve cells form and connect. The spinal cord is developing, and the nerves are starting to spread to the body. The neural tube closed last week, so the most critical period for folic acid is ending, but folic acid still matters for growth and for your own blood.
Face. The face is taking shape. Dark pigment forms in the eyes, and the lenses develop. The nostrils open, the upper lip forms and the mouth and tongue begin to form. The ears move into position, and the jaw grows. The eyelids start to form, and they will fuse shut and stay closed until about 26 weeks.
Arms and legs. The arm buds have grown, with small hand plates at the ends, and the first signs of fingers appear as ridges. The leg buds follow, with foot plates. Elbows and knees begin to bend. The limbs look like tiny paddles for now.
Gut and organs. The gut tube is lengthening and looping, and part of it grows into the base of the umbilical cord for a few weeks, which is normal and returns into the belly by about 12 weeks. The liver is large and makes blood cells. The pancreas, appendix, kidneys and lungs are forming in outline. Tooth buds begin to appear in the jaw.
Tail. The small tail at the base of the spine is shrinking and disappears over the next week or so.
Placenta and cord. The placenta is growing and attaching more firmly, and the umbilical cord is lengthening and developing blood vessels, two arteries and one vein, to carry blood between you and your baby. The yolk sac still supplies much of the nutrition, and the placenta takes over at about 10 to 12 weeks.
Amniotic sac. The embryo floats in a fluid-filled sac, which grows with it and protects it.
Movement. The embryo is beginning to make tiny movements, which a scan can sometimes see from about 7 to 8 weeks. You cannot feel them. You will feel your baby move at about 16 to 22 weeks.
Not yet formed. At 7 weeks, the baby has no fingers or toes that are separate, no visible genitals and no bones, only a cartilage framework. The baby is still called an embryo, and becomes a fetus at about 10 weeks.
7 weeks pregnant ultrasound
By 7 weeks, an ultrasound can show much more than at 5 or 6 weeks. Many doctors advise a first scan between 7 and 9 weeks, or earlier if you have pain, bleeding, uncertain dates, a history of ectopic pregnancy or miscarriage or fertility treatment.
What a scan shows at 7 weeks. A transvaginal scan, using a slim probe placed gently in the vagina, gives the clearest picture. An abdominal scan is less clear this early.
| Finding | What it is | What to know |
|---|---|---|
| Gestational sac | The fluid-filled sac in the womb | Usually round, with a thick bright rim, and should be in the womb |
| Yolk sac | A small ring inside the sac | Feeds the embryo. Normally 3 to 5 mm |
| Embryo | A small bean-shaped or comma-shaped structure | Measured as the crown-rump length, about 7 to 14 mm |
| Heartbeat | A flickering inside the embryo | Seen in most pregnancies from about 6.5 to 7 weeks |
| Number of embryos | One or two | Twins can be seen from about 6 weeks |
| Womb and ovaries | The wall of the womb, any fibroids or cysts and the corpus luteum, a normal cyst on the ovary that makes progesterone | Doctors check for anything unusual |
The embryo does not look like a baby yet. On the screen, it is usually a small white bean beside a dark ring, with a flickering dot, the heartbeat.
Dating. The crown-rump length gives the best estimate of your due date in the first trimester, accurate to within about 5 to 7 days. If it differs from your dates by more than a week, your doctor may adjust the due date. A smaller embryo often means ovulation was later than you thought, which is common and does not mean a problem.
Heartbeat. A heart rate of about 120 to 160 beats per minute is typical at 7 weeks. A slow rate, particularly in a small embryo, needs a repeat scan after a week.
What if no heartbeat is seen at 7 weeks? This is stressful, but a single scan is not always conclusive. If the dates were wrong, the heartbeat may not be visible yet. Doctors do not diagnose a miscarriage from one early scan unless the findings are clear. Commonly used criteria for a missed miscarriage are an embryo 7 mm or longer with no heartbeat, or a large sac with no embryo. If the findings are uncertain, doctors repeat the scan after 7 to 14 days. Ask your doctor what the scan shows, what it means and when to come back, and try to bring someone with you. Waiting is hard, so look after yourself.
What if the scan shows something else?
| Finding | What it may mean |
|---|---|
| A small bleed beside the sac (subchorionic haematoma) | Common cause of spotting. Often resolves. Rest and report heavy bleeding |
| A pregnancy outside the womb or nothing in the womb | Pregnancy of unknown location or ectopic. Needs urgent follow-up and sometimes treatment |
| An empty sac larger than expected | Possible failed pregnancy. A repeat scan confirms |
| Two embryos | Twins. Extra care is advised |
| A fibroid or ovarian cyst | Usually harmless and monitored |
| A thickened cervix or a low sac | Often fine, with a recheck |
Safety. Ultrasound uses sound waves, not radiation, and is safe at any stage when medically useful. Non-medical “keepsake” scans in the first trimester are not recommended.
Cost and quality. Prices vary widely. Ask what is included, who does and reports the scan, whether it is transvaginal and whether a doctor will explain the result. Keep the report and images in your prenatal card.
Your body at 7 weeks
Hormones. The placenta makes hCG, which doubles about every two to three days early on, then slows, and peaks at about 8 to 11 weeks. It is linked to nausea. Progesterone and estrogen continue to rise, relaxing smooth muscle, slowing digestion and making you tired.
The womb. It has grown to about the size of a small orange, and is still inside the pelvis. You cannot feel it from outside, and it does not make your belly look bigger. Any swelling is bloating.
Blood volume. It is rising, and will be up to 40 to 50 percent higher by the third trimester. You may feel dizzy, tired or breathless.
Breasts. They may feel full, heavy or tender, with darker nipples and more visible veins. These changes are normal.
Kidneys and bladder. You pass urine often, because your kidneys filter more blood and hormones relax the bladder.
Gut. Slow digestion causes bloating, gas, constipation and heartburn. Your sense of smell is sharper, and you may dislike foods you usually enjoy.
Mucus plug. A thick plug of mucus forms in the cervix, sealing it against infection. It will come away near the end of pregnancy.
Weight. Most people gain little or nothing in the first trimester, and some lose a little with nausea. Both are normal.
Skin and hair. A glow, acne, oily or dry skin and darker nipples can all appear. Hair may feel thicker.
Mood. Mood swings, tearfulness, irritability and anxiety are common, and they come from hormones and from the stress of waiting.
7 weeks pregnant symptoms
Symptoms often peak around 7 to 9 weeks, but they vary a lot.
| Symptom | How common | Why it happens | What helps |
|---|---|---|---|
| Nausea and vomiting | Very common | hCG and estrogen, a sensitive stomach | Small frequent meals, dry biscuits before getting up, ginger, cold sips of water |
| Tiredness | Very common | Progesterone, blood volume, energy use | Early bedtime, an afternoon rest, shared chores |
| Tender, swollen breasts | Common | Hormones | A soft, supportive cotton bra |
| Frequent urination | Common | More blood flow to the kidneys, relaxed bladder | Water through the day, less before bed, do not hold urine |
| Bloating and gas | Very common | Slower digestion | Smaller meals, avoid fizzy drinks, walk |
| Constipation | Common | Slower gut, iron tablets | Fibre, water, daily movement |
| Heartburn | Common | Relaxed valve at the top of the stomach | Smaller meals, avoid spicy and oily food |
| Mild cramps or pulling | Common | The womb stretching and settling | Rest, warm bath. See the warning signs below |
| Light spotting | Up to 1 in 4 | Hormones, a small blood clot, cervical changes | Wear a pad, tell your doctor |
| Milky discharge | Common | Hormones | Cotton underwear, no douching |
| Headaches | Common | Hormones, tiredness, dehydration | Rest, water, ask your doctor before taking medicine |
| Dizziness | Common | Low blood sugar, blood pressure changes | Eat regularly, stand up slowly |
| Food aversions and cravings | Very common | Hormones and a sharper sense of smell | Eat what you can tolerate |
| Metallic taste and extra saliva | Some people | Hormones | Rinse your mouth, suck a lemon sweet, spit if needed |
| Mood swings | Very common | Hormones and stress | Talk to someone you trust, regular meals and sleep |
| Vivid dreams, poor sleep | Common | Hormones | Regular bedtime, avoid screens at night |
| Acne or oily skin | Common | Hormones | Gentle washing, ask a doctor before using any acne product |
Do not start vitamin B6, anti-nausea medicine or herbal remedies without your doctor’s advice.
7 weeks pregnant with no symptoms
Many people worry when they have few or no symptoms at 7 weeks, especially when friends are very sick. In most cases, there is no reason to worry.
Why you may have no symptoms:
- Symptoms vary a great deal between people and between pregnancies
- Some people are less sensitive to hormones
- Symptoms come and go, and may be milder on some days
- The embryo is growing well even when you feel normal
What the evidence shows. Having few or no symptoms does not mean something is wrong. Many healthy pregnancies have little nausea or breast tenderness at this stage. A sudden loss of all symptoms, without bleeding or pain, is also not proof of a problem, because symptoms fluctuate. Having strong symptoms does not guarantee a healthy pregnancy either.
When to see a doctor. Go for a check if the loss of symptoms comes with bleeding or pain, if you have had a miscarriage or ectopic pregnancy before or if you simply need reassurance. A scan, at the right time, is the most reliable way to check that the pregnancy is growing. Try to book it for the time your doctor advises, because too early a scan can be falsely worrying.
Cramps at 7 weeks: normal or not?
Cramps are one of the most common worries in early pregnancy. Mild cramping is usually normal, but some cramps need a doctor.
| Normal cramps | Warning signs |
|---|---|
| Mild, period-like, pulling or twinges | Severe pain that does not ease |
| Come and go, and ease with rest, a warm bath or a change of position | Pain on one side, or sharp, stabbing pain |
| Happen with stretching, bending or passing gas | Pain with heavy bleeding, clots or tissue |
| Come with no bleeding, or only light spotting | Pain with dizziness, fainting, pale skin or a fast heartbeat |
| Improve after you pass stools or gas | Pain with shoulder-tip pain |
| Pain with fever, chills or foul discharge | |
| Pain with burning urination |
Why mild cramps happen. The womb is stretching and its ligaments are loosening, blood flow is increasing and digestion is slow, so gas and constipation cause pain. These are not a sign of miscarriage.
What helps: rest, a warm bath or a warm cloth on your lower belly, a change of position, fibre and water for constipation, and a gentle walk for gas. Paracetamol at the recommended dose is generally considered safe, but ask your doctor first.
When to go to hospital: for any of the warning signs above, particularly severe or one-sided pain, heavy bleeding or fainting. These can be signs of ectopic pregnancy or miscarriage.
Vaginal discharge at 7 weeks
An increase in thin, milky white discharge, called leukorrhoea, is a normal sign of pregnancy. It is caused by higher estrogen and more blood flow to the cervix and vagina, and it helps protect against infection.
Normal: thin, clear or milky, mild or no smell, no itching or burning. It increases as pregnancy goes on.
See a doctor if:
| Sign | Possible cause |
|---|---|
| Thick, white, like cottage cheese, with itching and soreness | Thrush (yeast infection), treated with an antifungal that is safe in pregnancy |
| Thin, grey or white with a fishy smell | Bacterial vaginosis, which needs antibiotics |
| Green, yellow or frothy with a bad smell | Trichomoniasis or other infection |
| Pink, brown or bloody | Spotting. Tell your doctor |
| Heavy and watery | Needs a check |
| With burning urination, fever or belly pain | Possible urinary or pelvic infection. See a doctor the same day |
What helps: cotton underwear, changing wet or sweaty clothes quickly, wiping from front to back, washing with water or a mild unscented soap and avoiding douching and perfumed products. Do not treat discharge yourself with pharmacy tablets, creams or herbal washes without a diagnosis.
Spotting, bleeding and miscarriage
Spotting at 7 weeks. About 1 in 4 pregnant people have some spotting in the first trimester, and most go on to have healthy babies. Common causes include hormone changes, a small blood clot beside the sac, a cervix that bleeds easily after sex or an internal examination and a small growth on the cervix.
What to do for light spotting: wear a pad, not a tampon, and note the colour, amount and any pain. Avoid sex until it stops, rest and call your doctor to report it and arrange a check. Light spotting that stops is usually fine.
Go to hospital the same day for:
- Bleeding that is red and heavy, or soaks a pad in an hour
- Bleeding with strong cramps or pain
- Passing clots or tissue
- Severe or one-sided belly pain
- Dizziness, fainting, pale skin or a racing heart
- Shoulder-tip pain
- Fever, chills or foul-smelling discharge
Miscarriage: what to know.
- About 10 to 20 in 100 known pregnancies end in miscarriage, most in the first 12 weeks.
- Chromosome problems in the embryo cause more than half of early miscarriages. They cannot be prevented and are nobody’s fault.
- Miscarriage is not caused by normal exercise, work, sex, stress, a shock, spicy food, hot or cold food, ripe fruit, a minor fall or an ordinary argument. Please do not blame yourself.
- The risk rises with age, previous miscarriages, uncontrolled diabetes or thyroid disease, smoking, alcohol and high caffeine intake.
- Once a heartbeat has been seen at 7 weeks, in a person with no other risk factors, more than 9 in 10 pregnancies continue.
- Signs include vaginal bleeding, often with cramps or back pain, passing clots or tissue and a loss of pregnancy symptoms. Not every bleed is a miscarriage.
If you are miscarrying, your doctor will examine you, and may arrange an ultrasound and blood tests. Options include waiting for it to pass naturally, medicine to help it pass and a small procedure. Heavy bleeding, fever, severe pain or fainting need urgent care. If you are Rh negative, ask about an anti-D injection after bleeding.
Grief. A miscarriage is a loss, and it is normal to feel sad, angry, guilty or numb. Give yourself time, talk to someone you trust and ask for help if sadness does not ease. Most people go on to have a healthy pregnancy. Doctors usually advise further tests only after two or three miscarriages.
Ectopic pregnancy warning signs
An ectopic pregnancy implants outside the womb, most often in a fallopian tube. It affects about 1 to 2 in 100 pregnancies. It cannot continue, and if the tube ruptures, it can cause life-threatening bleeding. Symptoms usually start between 5 and 9 weeks, so 7 weeks is a key time to know them.
Warning signs:
- Sharp, stabbing or persistent pain in the lower belly or pelvis, often on one side
- Vaginal bleeding, which may be light, dark brown or watery, or heavy
- Shoulder-tip pain
- Pain when passing stools or urine
- Dizziness, feeling faint or fainting
- Pale skin, a fast heartbeat, weakness or collapse
Higher risk: a past ectopic pregnancy, tubal or pelvic surgery, pelvic infection, an IUD in place when you conceived, fertility treatment, smoking and endometriosis. About half of ectopic pregnancies happen in people with no known risk factor.
What to do: go to a hospital emergency department at once, or call 999. Do not wait, and do not eat or drink if you may need surgery. Tell the staff you may be pregnant, and the date of your last period.
Treatment. Found early, an ectopic pregnancy can be treated with an injection of methotrexate. Otherwise, keyhole surgery removes it, sometimes with the tube. Early care protects your health and your fertility.
Symptoms and the sex of your baby
People often search for “7 weeks pregnant symptoms for a baby boy.” No symptom can tell you the sex of your baby.
| Belief | The truth |
|---|---|
| Severe morning sickness means a girl | Not proven. Some studies show a small difference, and many people with boys have severe nausea too |
| No morning sickness means a boy | No. Nausea varies for many reasons |
| Cravings for sweet or salty food | Cravings come from hormones and habits |
| Fast or slow heart rate | Heart rate does not predict sex. It changes with age and activity |
| Skin and hair changes, or the shape of your belly | Caused by hormones and your build. At 7 weeks there is no bump |
| Folk tests, charts, ring and thread, and apps | No better than a coin toss |
When can you really know?
| Method | When | Accuracy |
|---|---|---|
| Non-invasive prenatal blood test | From about 10 weeks | Very high, though done mainly to screen for chromosome conditions |
| Ultrasound | Sometimes at 12 to 14 weeks, reliably at 18 to 22 weeks | Good, but depends on the baby’s position |
| Amniocentesis or CVS | When done for medical reasons | Very accurate |
At 7 weeks, the genitals have not formed, so a scan cannot show the sex. The sex is set at conception, but it cannot be seen for several more weeks.
A healthy baby is what matters. Choosing or acting on the sex of a baby, including pressure to have a son or ending a pregnancy because of the sex, is harmful and unethical. If anyone presses you, tell your doctor or call the national helpline 109, which supports women who face pressure and violence.
Twins at 7 weeks
Twins can sometimes be seen from about 6 weeks, and they are clearer at 7 to 8 weeks. Twins are more likely if you have had fertility treatment, have a family history of non-identical twins, are older or have had twins before.
| Type | What it is | Features |
|---|---|---|
| Non-identical (dizygotic) | Two eggs fertilised by two sperm | Two sacs, two placentas, and two embryos |
| Identical (monozygotic) | One egg splits | May share a placenta or a sac, which carries extra risks and needs closer monitoring |
Signs that may suggest twins: a higher hCG, more severe nausea, extreme tiredness and a bigger-than-expected womb, but none is reliable. A scan confirms.
If you are carrying twins: you will usually have extra scans, closer monitoring and advice about food, supplements and rest. Twin pregnancies have a higher risk of anaemia, high blood pressure, early labour and complications, so keep every visit, take iron and folic acid as advised and plan to give birth in a hospital with a newborn unit.
Nausea, vomiting and hyperemesis
Nausea affects about 7 in 10 pregnant people, and vomiting about half. It often starts at about 5 to 6 weeks, peaks at 9 to 10 weeks and eases by 12 to 14 weeks, though it lasts longer for some. It is called morning sickness, but it can happen at any time of day or night.
What helps:
- Eat a few dry biscuits, toast or puffed rice before getting out of bed
- Eat small meals every two to three hours, so your stomach is never empty
- Avoid triggers, such as strong smells, spicy, oily or very sweet food and cooking fumes. Ask someone else to cook, if you can
- Sip cold fluids through the day. Try lemon water, ice chips or oral rehydration solution
- Try ginger, in tea, biscuits or food, which is generally safe in food amounts
- Get fresh air, keep your room cool and rest
- Brush your teeth after vomiting, and rinse your mouth with water to protect the enamel
- Eat protein with meals, which may settle your stomach
- Take iron-folic acid with food or at night, and ask your doctor if iron makes nausea worse
- Do not worry about “eating healthily” when you feel awful. Eat what you can, and catch up later
If nausea is bad, your doctor may advise vitamin B6, with or without doxylamine, or another anti-nausea medicine. Do not take them without advice.
Hyperemesis gravidarum. About 1 in 100 pregnant people have severe, persistent vomiting that needs treatment. Signs are:
- Vomiting many times a day, and being unable to keep down food or water
- Weight loss of more than 5 percent of your body weight
- Dark urine, passing very little urine, a dry mouth, dizziness and a fast heartbeat
- Weakness, and being unable to do daily tasks
- Vomiting blood, or severe belly pain
See a doctor the same day. Treatment includes fluids through a drip, anti-nausea medicine, vitamins and sometimes a short stay in hospital. It is not caused by anything you did, it is treatable and you do not need to push through it.
Food, folic acid and supplements
Folic acid. Folic acid helps the neural tube close and lowers the risk of neural tube defects. The tube has closed by now, but folic acid still helps your baby’s growth and your own blood. Take 400 micrograms a day until 12 weeks, or the higher dose your doctor prescribes if you have diabetes, epilepsy, a family history of neural tube defects, obesity or thalassaemia. If you have not started, start today.
Iron. Most doctors in Bangladesh prescribe iron-folic acid tablets from the first visit, usually 60 mg of iron and 400 micrograms of folic acid a day, to prevent anaemia. Take them as prescribed. If iron upsets your stomach, take it with food or at night, and ask your doctor before stopping.
Vitamin D. It helps your body use calcium. Many women in Bangladesh have low levels, especially if they cover their skin or spend most of the day indoors. Ask your doctor whether you need a supplement.
Iodine. Use iodised salt in your cooking. Iodine supports your baby’s brain development.
Calcium. Supplements are usually advised from about 20 weeks. Ask your doctor.
Vitamin A. Do not take high-dose vitamin A supplements, which can harm the baby. Eat vitamin A in food, such as leafy greens, carrots, pumpkin, mango, eggs and milk.
Do not take extra supplements or herbal products without advice. More is not better.
Eat more of:
- Protein: well-cooked eggs, fish, chicken, lentils (dal), beans and milk
- Iron-rich foods: leafy greens (shak), lean meat and lentils, with lemon or guava for vitamin C
- Folate-rich foods: leafy greens, lentils, beans, oranges and fortified foods
- Calcium: milk, yogurt, and small fish eaten with the bones
- Fruit and vegetables: a variety of colours every day
- Whole grains and fibre: brown rice, whole wheat roti and oats
- Healthy fats: well-cooked oily fish, nuts and seeds
- Water: 8 to 10 glasses a day, more in hot weather
How much to eat. You do not need extra calories in the first trimester. Do not “eat for two”. If nausea limits what you eat, eat what you can, in small amounts. Tell your doctor if you are losing weight quickly.
7 weeks pregnant: what to avoid
| Avoid | Why | What to do instead |
|---|---|---|
| Alcohol | Can harm your baby at any stage. No safe level is known | Avoid completely |
| Tobacco in any form, including zarda, jorda, gul, betel quid with tobacco, and smoke from others | Raises the risk of miscarriage, low birth weight and early birth | Stop completely. Ask your doctor for help to quit |
| Recreational drugs | Can harm the baby | Stop. Ask for support without fear of judgement |
| Raw or undercooked meat, poultry and eggs | Salmonella, toxoplasma and other germs | Cook until firm and hot all the way through |
| Raw fish and shellfish | Germs and parasites | Eat well-cooked fish |
| Large predatory fish such as shark, swordfish and king mackerel | High mercury harms the developing brain | Choose small and medium fish such as rui, hilsa, tilapia and mola |
| Unpasteurised milk, cheese and juice | Listeria and other germs | Use boiled or pasteurised milk |
| Unwashed raw produce and cut fruit from unclean places | Germs and soil parasites | Wash well, peel, and choose freshly cooked food |
| Street food from places with poor hygiene | Stomach infections and dehydration | Choose hot, freshly cooked food from clean places |
| Untreated water and ice | Germs. Tube well water may also contain arsenic | Drink boiled or filtered water. Use tube wells tested and marked safe |
| Too much caffeine | Linked to miscarriage and low birth weight | Keep below about 200 mg a day, which is one or two cups of tea or one small coffee. Count cola and energy drinks |
| Liver in large amounts, and high-dose vitamin A supplements | Very high vitamin A can harm the baby | Eat liver rarely and in small amounts, if your doctor agrees. Do not take vitamin A supplements |
| Unripe or semi-ripe papaya | Contains latex that may cause contractions | Avoid. Ripe papaya in normal amounts is generally considered fine, but ask your doctor |
| Herbal tonics, kabiraji remedies and unregistered products | May be unsafe | Avoid unless your doctor approves |
| Hot baths, saunas and steam rooms | Overheating in the first trimester is not advised | Warm showers are fine |
| Cat litter and raw meat handling | Toxoplasma | Wear gloves, wash hands, and ask someone else to clean the litter |
| Strong chemicals, paints, solvents and pesticides | Can harm the baby | Avoid, or use protection and ventilation |
| Mosquito coils and incense smoke | Smoke harms your lungs | Use nets instead |
| Ibuprofen, aspirin and diclofenac, unless prescribed | Not advised in pregnancy | Use paracetamol at the recommended dose, and ask your doctor |
| Isotretinoin, retinoids and some acne treatments | Can cause birth defects | Tell your doctor before you take any acne medicine |
| Unnecessary X-rays | Radiation | Tell the staff you may be pregnant, and ask if the test is needed |
Myths to ignore. Eating banana, ripe papaya, pineapple, eggplant, duck eggs, hot food, cold food or jackfruit in normal amounts does not cause miscarriage. Many old rules about “hot” and “cold” foods have no medical basis, and they can leave a pregnant woman short of nutrients.
Medicines. Always ask a doctor or pharmacist before taking any medicine, including herbal and over-the-counter products. Do not stop medicine for a long-term condition, such as epilepsy, diabetes, thyroid disease, asthma or high blood pressure, without talking to your doctor. A fever of 38°C or more needs a doctor, and in Bangladesh it may be dengue, so do not treat it at home.
Urine infections and dental care
Urinary tract infections. Hormones relax the urinary tract, so infections are more common in pregnancy. Some cause no symptoms, called asymptomatic bacteriuria, which affects about 2 to 10 in 100 pregnant people. If untreated, an infection can spread to the kidneys and raise the risk of early labour. That is why your urine is tested at your first visit.
Symptoms: burning when passing urine, urgency, passing small amounts often, cloudy or strong-smelling urine, lower belly pain, blood in the urine, fever, chills or pain in the back or sides. See a doctor the same day. A urine test confirms it, and an antibiotic that is safe in pregnancy treats it. Finish the full course, and do not take antibiotics from a pharmacy without a prescription.
How to lower the risk: drink plenty of water, pass urine when you need to and do not hold it, pass urine after sex, wipe from front to back, wear cotton underwear and avoid scented soaps and douches.
Dental care. Hormones make gums swell and bleed, and nausea and vomiting expose teeth to acid. Gum disease is linked to early birth, so look after your mouth.
- Brush twice a day with fluoride toothpaste, floss gently and use a soft brush
- Rinse your mouth with plain water after vomiting. Wait about 30 minutes before brushing, to avoid brushing softened enamel. A rinse with a little baking soda in water also helps neutralise acid
- Have a dental check. Dental treatment, including cleaning and fillings, is safe in pregnancy, and the second trimester is the best time for non-urgent work. Treat pain and infection at any time
- Tell your dentist you are pregnant before any X-ray or medicine
Your first prenatal visit
The World Health Organization recommends at least eight contacts with a health professional during pregnancy, with the first before 12 weeks. If you have not booked yet, do it now, ideally for 8 to 10 weeks.
What usually happens:
- A review of your medical history, previous pregnancies, medicines, allergies and family history
- Blood pressure, weight, height and a physical check
- Confirmation of your due date, often by scan
- A discussion of food, supplements, habits and symptoms
- Blood and urine tests, which may include:
| Test | Why |
|---|---|
| Blood group and Rh factor | To plan anti-D if you are Rh negative |
| Hemoglobin | To check for anaemia, which is common in Bangladesh |
| Blood sugar | To check for diabetes |
| Urine test and culture | For infection and protein |
| Hepatitis B, HIV and syphilis | Treatment in pregnancy protects your baby |

Write down the answers.
Exercise, sleep and sex
Exercise. Light to moderate exercise is safe and good for most healthy pregnancies. Walk about 30 minutes on most days. Swimming, gentle yoga and stretching are good. You should be able to talk while you exercise. Avoid contact sports, hot yoga, activities with a risk of falls and heavy lifting. Stop and call your doctor if you have pain, bleeding or dizziness.
Sleep. Many people need more sleep in the first trimester, and short naps help. Go to bed earlier, keep your room cool and avoid screens at night.
Sex. It is safe for most healthy pregnancies and does not cause miscarriage. Avoid it if you have bleeding or pain, or your doctor has told you to rest. Desire may rise or fall, and both are normal.
Everyday life in Bangladesh
Dengue and mosquito bites. Dengue spreads by mosquito bites, and it can be serious in pregnancy. Remove standing water around your home, use a mosquito net and a pregnancy-safe repellent, wear long sleeves and see a doctor straight away for any fever. Do not take ibuprofen or aspirin for fever unless your doctor says so.
Heat. Hot, humid weather can dehydrate you and make nausea worse. Drink water through the day, wear loose cotton clothes, rest in the shade and avoid long hours in direct sun. Oral rehydration solution helps if you have been sweating or vomiting a lot.
Safe water. In many areas, groundwater from tube wells contains arsenic. Drink water from tube wells that have been tested and marked safe, usually painted green, and avoid those marked red. Boil or filter drinking water for germs. Boiling does not remove arsenic.
Cooking smoke. Smoke from wood, dung, crop waste and kerosene harms your lungs and can lead to low birth weight. Cook outdoors or with good ventilation, use a cleaner stove if you can and take breaks from the kitchen.
Fasting. If you plan to fast, talk to your doctor first. Many doctors advise against fasting in pregnancy, particularly with nausea, because it can cause dehydration and low blood sugar. Islamic scholars allow an exemption for pregnant women if fasting may harm them or their baby.
Travel and transport. Short trips are usually fine. Nausea and tiredness can make bumpy rickshaw, CNG and bus rides uncomfortable. Choose smoother routes, sit with your back supported and avoid crowded vehicles where you could be pushed. Wear a seat belt in a car.
Work. Most people can keep working. Tell your doctor about night shifts, chemicals, heavy lifting or long standing. Take breaks to eat and drink. Under Bangladesh’s labour law, working mothers in the private sector are entitled to 16 weeks of paid maternity leave, eight before and eight after the birth, and government employees receive six months. You will need to give notice later, so check your contract.
Feelings, your partner and telling people
Your feelings. Early pregnancy brings a mix of joy, fear, disbelief, worry and tiredness. If the pregnancy was unplanned, you may feel unsure, and that is normal. Many people worry about miscarriage, and waiting for the first scan is hard.
What helps:
- Talk to your partner, a trusted friend or relative, or your doctor
- Keep a routine, with regular meals, daylight and a short walk
- Rest when you can
- Limit searching online for frightening stories. Ask your doctor instead
- Take it one day at a time
When to get help. Feeling very low, hopeless or anxious for two weeks or more, losing interest in things, being unable to sleep or eat or having thoughts of harming yourself needs attention. Depression and anxiety in pregnancy are common and treatable. Tell your doctor. If you have thoughts of harming yourself, go to the nearest hospital or call 999.
Your partner. Partners may feel excited, anxious or left out. They can help by coming to visits, cooking or avoiding strong smells, sharing chores, helping you rest and listening. Talk about your hopes, fears and plans, and look after each other.
Telling people. Many people wait until after the first scan or until 12 weeks, because the risk of miscarriage is higher early on. It is your choice. You might tell a few people you trust first, so you have support if things go wrong. You do not owe anyone an explanation if you prefer to wait.
If you feel unsafe. If you feel unsafe at home, tell your doctor or a trusted person. In Bangladesh you can call the national helpline 109 for support with violence against women and children. It is free.
If the pregnancy is unplanned or unwanted. You have the right to confidential, non-judgemental advice, and time matters. Talk to your doctor or a trusted health worker about your options soon. Menstrual regulation, a legal procedure in Bangladesh within the first weeks after a missed period, is available at government and approved NGO facilities, and it is time-limited, so ask early. Do not use unsafe methods, herbal mixtures or unlicensed providers, which can cause serious harm or death. Ask your doctor or the nearest family planning clinic for safe options and support.

FAQ
How big is the baby at 7 weeks?
About 1 cm from head to bottom, roughly the size of a blueberry, and less than a gram. The range is about 7 to 14 mm.
What is the height of the baby at 7 weeks of pregnancy?
Doctors measure the length from the crown of the head to the bottom, about 1 cm at this stage. It is not measured as a height. The embryo grows about a millimetre a day.
How many months pregnant am I at 7 weeks?
About one and three-quarter months. You are in the second month of pregnancy, not the first.
Can you see the heartbeat at 7 weeks?
Yes, in most pregnancies, on a vaginal scan. The heart rate is typically about 120 to 160 beats per minute. If it is not seen, doctors usually repeat the scan in 7 to 14 days, because dates may be off.
What does an ultrasound at 7 weeks show?
A gestational sac, a yolk sac, a small bean-shaped embryo with a flickering heartbeat and the number of embryos. It cannot show the sex, fingers or most organs.
Are cramps at 7 weeks normal?
Mild, period-like cramps are common as the womb stretches. See a doctor for severe or one-sided pain, pain with heavy bleeding, dizziness, fainting, shoulder-tip pain or fever.
Is increased discharge normal at 7 weeks?
Yes. A thin, milky, mild-smelling discharge is common. See a doctor for a bad smell, itching, burning, green or yellow colour or blood.
I have no symptoms at 7 weeks. Should I worry?
Usually no. Symptoms vary a great deal, and many healthy pregnancies have few. See a doctor if you also have bleeding or pain, have had a miscarriage or ectopic pregnancy before or need reassurance.
Can symptoms tell me if I am having a boy?
No. Morning sickness, cravings, heart rate and belly shape do not predict sex. A blood test from about 10 weeks or an ultrasound at 18 to 22 weeks can show it.
What should I avoid at 7 weeks pregnant?
Alcohol, tobacco in any form, drugs, raw or undercooked meat, eggs and fish, large predatory fish, unpasteurised dairy, unwashed produce, untreated water, high-dose vitamin A, herbal tonics, hot baths and any medicine your doctor has not approved. Limit caffeine to about 200 mg a day.
Is it safe to exercise at 7 weeks?
Yes for most healthy pregnancies. Walking, swimming, gentle yoga and stretching are good. Avoid contact sports, hot yoga, heavy lifting and activities with a risk of falls.
