10 Weeks Pregnant
You’re 10 weeks pregnant — in the first trimester, and 30 weeks to go until your due date. Your baby is about the size of a kumquat this week.

Last week your baby was about the size of a grape; this week it's grown to roughly a kumquat.
Sizes are averages from standard fetal-growth references. Every baby grows at its own pace — your provider tracks yours at scans.
Baby development at week 10
Vital organs — kidneys, intestines, brain, and liver — are now working. Tiny tooth buds are forming under the gums, and the arms can bend at the elbow. Fingernails and fine hair begin to appear, and the fetus is swallowing and kicking, though still far too small to feel. About the size of a kumquat.
Your body at 10 weeks
Common symptoms many people notice around week 10 include:
- Nausea often starts to ease for some
- Visible round-ligament aches as the uterus expands
- Slight increase in vaginal discharge
- Possible appearance of visible veins on the belly and breasts
Symptoms vary enormously from person to person and pregnancy to pregnancy. Not having a symptom on this list is just as normal as having it.
Tips for week 10
- Non-invasive prenatal testing (NIPT) can be done from around week 10
- A pregnancy-support pillow can help early sleep changes
- Keep hydrated to support the increase in blood volume
What trimester is 10 weeks?
Week 10 falls in the first trimester. As a quick map: the first trimester runs weeks 1–13, the second covers weeks 14–27, and the third is week 28 through birth (a due date is set at 40 weeks). Want your own dates? Our Pregnancy Due Date Calculator shows your due date and exactly how far along you are today.
The first trimester (weeks 1–13) is when the baby's major organs and body systems form, and when pregnancy symptoms like nausea and fatigue are usually strongest. It's also when most prenatal care begins — the dating scan, early bloodwork, and (if you choose) genetic screening all happen in this window.
