Week 9 of pregnancy: Last Weeks as an Embryo

The embryonic stage is nearly over and nausea often peaks. Set up a safe exercise routine and learn to tell normal frequent urination from a UTI.

Last updated 28 September 2026

What's happening this week?

This is one of the last weeks your baby is called an embryo. By about 10 weeks most major structures will have formed, and this week's finishing touches include eyelids, toes and the first tooth buds. For many people nausea is at its worst, tiredness is heavy and toilet trips are frequent. Two things are worth doing now: make sure your first antenatal visit is booked, and plan how you will stay active safely.

Baby's development

Your baby is about seven weeks past fertilisation, close to the end of the embryonic period. That stage closes at about 10 weeks of pregnancy, and the stretch from about week 3 to week 10 is when nearly every major organ is laid down. What happens now is mostly refinement rather than new beginnings.

The eyelids are growing forward over the eyes and will fuse shut by about 10 weeks, staying closed until the late second trimester. Toes are becoming visible, and the buds that will later become teeth and taste buds are beginning to form. Inside the chest, the heart has spent the last couple of weeks dividing into chambers, and that process is finishing around now.

The embryo has been making small, spontaneous movements since about 7–8 weeks. They can be seen on ultrasound but are far too slight to feel; most people first notice movement somewhere between 16 and 24 weeks. A scan now shows clear cardiac activity, yet a clinic's hand-held Doppler often cannot pick up the heartbeat until about 10–12 weeks, so not hearing it at 9 weeks is not a sign of a problem.

Gestational age

Your baby is measured from head to bottom, called crown–rump length, and is typically about 2–3 cm now. The 2.3 cm and 2 g shown are averages with a normal spread either side, and a grape is only a rough guide.

Your body this week

Pregnancy hormones are running high. hCG, the hormone a pregnancy test detects, climbs until it peaks at around 8–11 weeks, which is why nausea is often strongest around week 9. Progesterone relaxes smooth muscle throughout the body and contributes to bloating, constipation and the heavy tiredness that is common between about 6 and 12 weeks.

Your kidneys are handling more blood flow and your blood volume has already begun to rise, so you may pass urine more often even though your uterus is still small and tucked inside the pelvis. Later, the growing uterus pressing on the bladder adds to this.

Emotionally this can be a strange in-between time: you may feel very pregnant but not look it, and you may not have told many people. Mood swings, worry and tearfulness are common. If low mood or anxiety is there most days for two weeks or more, tell your doctor or midwife.

Symptoms you may notice

Every pregnancy is different - you may have some, all or none of these.

Frequent urination: Hormones and extra blood flow make your kidneys produce more urine. It should not hurt. Burning, stinging, urgency, or cloudy or smelly urine can mean an infection, so tell your doctor the same day.
Nausea and vomiting: Often at its peak now, and it can strike at any time of day. Small, plain, frequent meals help many people. If you cannot keep fluids down for about 24 hours, call your doctor the same day.
Tiredness: Progesterone and the work of building the placenta are exhausting. Rest when you can and go to bed earlier for a while; for most people energy returns in the second trimester.
Bloating and constipation: Progesterone slows the gut. Regular meals, fluids, fibre and daily movement help. Severe or one-sided pain is not ordinary bloating and needs checking.

Medical care and tests

First antenatal (booking) visit
Routine
By 12 weeks in India; by 10 weeks in the UK
If you have not been seen yet, arrange it now. In India, registration and the first check-up should happen within 12 weeks, when your booking blood and urine tests are done; in the UK, booking is planned by 10 weeks.
Early pregnancy scan
Commonly offered
Often 6–9 weeks in private care
Many private obstetricians in India arrange one to confirm the pregnancy is in the uterus, see cardiac activity, count the babies and check dates. Not everyone needs it. Every pregnancy scan in India is recorded on a PCPNDT Form F.
Planning first-trimester screening
Varies by provider
Book for 11+0 to 13+6 weeks
The NT scan and double marker blood test have a fixed window that opens in two weeks. They are optional; if you are considering them, ask where they are done and book a date now. The week 11 page explains them.
Urine culture
Only if needed
If you have urine symptoms; US routine at 12–16 weeks
If you have symptoms of a urine infection, a sample may be sent to identify the bacteria and the right antibiotic. In India a urine dipstick at each visit is standard; in the US a culture is routine in early pregnancy.

Visit and test schedules differ between government and private care and between doctors. In India, government facilities provide antenatal check-ups free of cost; follow the plan your own doctor, ANM or health centre gives you.

Nutrition this week

Protein needs rise in the second and third trimesters, so build the habit now: a protein food at each main meal, such as a katori of dal, sambar, rajma, chole or moong, or some paneer or dahi.
India's dietary guidelines build the pregnancy plate around daily pulses, milk or curd, vegetables, fruit, whole cereals and some nuts and seeds. A serving of dal can be swapped for egg, fish or chicken if you eat them.
Most vegetarian readers rely on dairy and pulses for protein. If you eat eggs, cook them until the white and yolk are firm.
When nausea makes a full plate impossible, small protein snacks are often easier: roasted chana, peanuts, a glass of milk, a bowl of dahi or a besan chilla.

Movement and exercise

Unless your doctor advises otherwise, aim for at least 150 minutes a week of moderate activity, for example 30 minutes on five days, plus some gentle strengthening. If you were already active, you can usually carry on with adjustments.
Use the talk test: you should be able to hold a conversation while you exercise. Walking, swimming, stationary cycling, low-impact aerobics and prenatal yoga are good choices. Avoid contact sports, activities with a high risk of falls, scuba diving, hot yoga and overheating.
Stop and get advice if you have bleeding, fluid leaking, dizziness, chest pain, headache, calf pain or swelling, or feel breathless before starting. Some heart, lung and pregnancy conditions need tailored advice.

Things to keep in mind

Keep drinking normally. Cutting down on fluids to reduce toilet trips makes urine infections and constipation more likely.
Heavy tiredness is expected now. If you work, it may help to move demanding tasks to the time of day you feel best and take short breaks.
Avoid hot tubs, saunas and steam rooms, particularly in the first 12 weeks, because overheating in early pregnancy is a concern.
If you are waiting before sharing your news, think about who you would turn to if you felt unwell or noticed a worrying symptom.

When to contact your doctor

Call your doctor or midwife the same day if you have

You cannot keep food or fluids down for about 24 hours, or your urine is dark and scanty.
You have burning or stinging when passing urine, or cloudy or smelly urine.
You notice light bleeding or spotting.
You have a temperature of 38°C or more.
Low mood or anxiety has been there most days for two weeks or more.

Get emergency care now if you have

Heavy bleeding, such as soaking a pad in an hour or passing clots.
Severe or constant abdominal pain.
One-sided lower abdominal pain with dizziness, fainting or shoulder-tip pain.
Urine symptoms with fever, back or side pain and vomiting.
Thoughts of harming yourself.

In India, call 108 for an ambulance, 102 for free transport for pregnant women in many states, or 112 for any emergency - or go straight to your nearest hospital with a maternity unit.

If something feels wrong, trust that feeling and call - you never need to wait for your next appointment.

Frequently asked questions

Is it normal to need to pass urine so often at 9 weeks?

Yes, for many people. Pregnancy hormones and increased blood flow through the kidneys mean more urine is made, even before the uterus is big enough to press on the bladder. It should not hurt or burn. If it does, or your urine is cloudy or smelly, or you have a fever or back pain, it could be an infection and needs checking the same day.

Can I start exercising now if I was not active before pregnancy?

In an uncomplicated pregnancy, yes. Start with short, gentle walks and build up gradually towards 150 minutes a week of moderate activity, using the talk test and avoiding overheating. Ask your doctor first if you have a heart or lung condition, bleeding or another complication.

Is my baby a fetus yet at 9 weeks?

Not quite. Doctors use the word embryo until the end of the eighth week after fertilisation, which is about 10 weeks counted from your last period. By then most major structures have formed and the name changes to fetus. It marks a stage of development; nothing sudden happens on a particular day.
