What's Happening With Your Baby
The brain is growing fast and head circumference is increasing noticeably. Bone marrow has fully taken over red blood cell production. Lanugo hair is beginning to shed.
What's Changing For You
Mood swings can return. Sleep quality is poor. Colostrum — the first milk — may leak from your breasts.
To Do This Week
Start learning about breastfeeding; look into a class or a lactation consultant.
Keep breast pads on hand; leaking colostrum is normal.
For insomnia, cut evening screen time and try a warm shower and breathing exercises.
Frequently Asked Questions
How many months is 30 weeks pregnant?
Week 30 of pregnancy falls in month 7 and in the third trimester. Pregnancy months don't run in neat four-week blocks, so the week-to-month conversion rarely lands on a whole number — which is why pregnancy is tracked in weeks.
How big is the baby at 30 weeks?
At 30 weeks your baby is roughly the size of a cabbage: around 39.9 cm long and 1319 grams. These are averages; clear variation between babies is normal, and what matters is the growth curve your doctor is tracking.
How long is left at 30 weeks pregnant?
Assuming a 40-week pregnancy, you have around 10 weeks left at week 30. Most births happen between weeks 37 and 42, so a due date is a range rather than a fixed day.
What should I watch out for at 30 weeks?
Start learning about breastfeeding; look into a class or a lactation consultant. Keep breast pads on hand; leaking colostrum is normal. For insomnia, cut evening screen time and try a warm shower and breathing exercises.

When To Seek Care Immediately
Whatever week you are in, contact your doctor or the nearest health facility without waiting if you have: vaginal bleeding or fluid loss, severe persistent abdominal pain, a severe headache, blurred vision or flashing lights, sudden swelling of the hands or face, a fever above 38 °C, burning on urination with fever, persistent vomiting, fainting, or — after week 28 — a clear reduction in your baby's movements. In these situations reach real medical care rather than an app or a web search.
