10 weeks pregnant.
The fetus can flex tiny limbs, swallow amniotic fluid, and kick — though you can't feel it yet.

Your baby this week
Recognizably human — rounded head, visible nose, distinct chin. Movements are happening though far too small to feel.
- Tiny limbs flex and stretch
- Swallowing begins
- Nails start to form
- Vital organs functioning
What may be changing in your body
Some morning sickness may start easing. Breast changes continue — they may already be a cup size bigger. Vivid dreams are also common right now.
Nausea beginning to plateau
For many, week 10 is the summit — sickness holds steady and then starts a slow descent over the coming weeks. Hold on; relief is genuinely coming.
Visible veins
Blood volume is climbing steeply, and blue veins may stand out across your chest and belly. This is your expanding supply network, not a problem.
Round ligament twinges beginning
As the uterus rises out of the pelvis, brief pulling sensations on either side of the lower belly can start. Sudden movements — sneezing, standing quickly — often trigger them.
Constipation and wind
Slowed digestion continues, and iron supplements can make it worse. Fluids, fibre and movement remain the best remedies; ask your pharmacist before using laxatives.
Mild swelling of the gums
Pregnancy gingivitis — puffy gums that bleed when brushing — often starts in the first trimester. Keep brushing and flossing gently; do not skip the dentist.
Fainting or palpitations — when to call
Feeling briefly light-headed is common, but actual fainting, a racing heart at rest, or chest pain should be reported promptly. Call your midwife or doctor to get checked.
Your week 10 checklist
- Confirm your dating scan appointment and any screening bloods that go with it
- Book a dental check-up if you have not — pregnancy makes gum care matter more
- Start a simple pelvic floor routine — a few sets of squeezes daily, decades of benefit
- If travelling later in pregnancy, check your travel insurance covers pregnancy now rather than at the airport
A useful partner move this week
The dating scan is likely within a fortnight — arrange your time off now, because being there matters and the appointment times rarely flex. In the meantime, take on the errands that involve queues and standing, since light-headedness is common this week. A cushion, a glass of water and an unprompted cup of decaf go further than you would think.
What comes next
By the end of week 12, the highest-risk period for miscarriage will be behind you. Energy often returns in the second trimester.
Common questions
When does the risk of miscarriage drop?
Risk falls steadily through the first trimester: once a heartbeat is confirmed around 8 weeks the risk is already low, and by the end of week 12 the large majority of ongoing pregnancies continue safely. This is why many people wait until after the dating scan to announce. Your own history and age adjust the picture, so ask your midwife for numbers specific to you.
What is the difference between NIPT and the combined test?
The combined test (around 11 to 14 weeks) uses an ultrasound measurement plus maternal blood markers to estimate the chance of Down's, Edwards' and Patau's syndromes. NIPT analyses fragments of placental DNA in your blood and is considerably more accurate as a screen, though it is often paid-for or offered only after a higher-chance combined result. Both are screening tests, not diagnoses — a higher-chance result leads to an offer of diagnostic testing.
Can I dye my hair while pregnant?
Yes — hair dye is generally considered safe in pregnancy, as very little chemical is absorbed through the scalp. If you want extra caution, wait until after the first trimester, use highlights rather than root-touching colour, or choose semi-permanent vegetable dyes. Ventilate the room well and do a strand test, since hair can respond differently to dye during pregnancy.
How many months is 10 weeks pregnant?
Pregnancy months do not divide evenly into weeks, so clinicians date pregnancy in weeks. At 10 weeks, you are in trimester one.
