9 weeks pregnant: the hormone peak, and a face taking shape
Often one of the toughest weeks for nausea and fatigue, because pregnancy hormones are at their peak. It does ease. Here is what helps meanwhile.

In short
At 9 weeks you are in month three of the first trimester. The NHS says your baby is about 22 mm from head to bottom, with eyelids, a little mouth and a tongue with tiny taste buds. The pregnancy hormone hCG is at its peak, which is why you may feel rough. The one thing to do this week: eat little and often and accept every offer of help.
Where you are at 9 weeks
Nine weeks is the start of month three in Cleveland Clinic's grouping, and you are about a month from the second trimester. Your breasts may be bigger and your waist thickening a little. Check your exact week and day with the pregnancy week calculator.
Your baby this week
The NHS gives a length of around 22 mm from head to bottom and compares your baby to a strawberry.
- The face is more recognisable: eyelids protect the eyes, and there is a little mouth and a tongue with tiny taste buds (NHS).
- Hands and feet are developing, with grooves where fingers and toes will be.
- The heart, brain, lungs, kidneys and gut are all developing, and bones are starting to form.
- Cleveland Clinic adds that the beginnings of teeth are forming, the head is still about half of the body length, and your provider may be able to hear the heartbeat with a Doppler.
- The genitals are starting to take shape, but the NHS says you probably will not find out the sex until the anomaly scan.
Your body: why this week can feel hard
The NHS explains that hCG, the pregnancy hormone, has been doubling every 2 or 3 days and peaks at around 9 weeks, alongside higher oestrogen and progesterone. That combination is behind the extreme tiredness, nausea and the emotional rollercoaster many people describe.
Snacks that help. Eating little and often keeps blood sugar steadier, which the NHS says can reduce nausea. Its ideas: a boiled egg with wholemeal toast, hummus with carrot sticks, pitta with grated cheese.
About remedies. A Cochrane review (Matthews 2015) found limited, inconsistent evidence for ginger, acupressure and vitamin B6, and no strong evidence for any single option. If nausea is wearing you down, ask about treatment rather than pushing through.
Other symptoms the NHS lists now: headaches, a metallic taste, a heightened sense of smell, bloating, cramping like period pain, darker patches on the face (chloasma) and thicker, shinier hair.
Is this normal? When to call
Call your midwife, GP or NHS 111 (UK), or your OB-GYN or midwife (US), if you cannot keep fluids down for 24 hours, your urine is very dark, or you feel faint on standing (NHS). ACOG adds: nausea that starts for the first time after 9 weeks should be checked. For bleeding or one-sided pain, call your early pregnancy unit or provider the same day. Call 999 or 911 for heavy bleeding with severe pain, shoulder pain or fainting.
If the fear of miscarriage keeps you up at night, you are far from alone. ACOG says it affects about 10 in 100 known pregnancies and is usually random. If you need support, Miscarriage UK (0303 003 6464) and Share Pregnancy and Infant Loss Support in the US are free.
Appointments and tests coming up
- US: ACOG says first-trimester screening (a blood test plus an ultrasound) is usually done between 10 and 13 weeks, and cell-free DNA screening can be done from 10 weeks, with results in about a week. Screening is optional: ask what each result would mean for you.
- UK: if your booking appointment has not happened yet, it should be in the next few weeks (8 to 12 weeks, NHS). You will be offered screening for infectious diseases and conditions such as Down's syndrome.

Questions parents ask
How big is my baby at 9 weeks pregnant?
The NHS says around 22 mm from head to bottom, which it compares to a strawberry. Cleveland Clinic notes that the head is still about half of the baby's length at this stage.
What are the signs of miscarriage at 9 weeks?
The NHS says the main sign is vaginal bleeding, sometimes with cramping in the lower tummy or tissue passing, though bleeding has other causes too. Call your early pregnancy unit, NHS 111 or your OB-GYN; call 999 or 911 for heavy bleeding with severe pain or faintness. ACOG says early loss is usually random and not caused by anything you did.
When will morning sickness stop?
ACOG says that for most people nausea goes away by 14 weeks, though for some it lasts longer. The NHS guide notes that many people start to feel much better in the second trimester.
