Week 35 is weight-gain season: nearly all gain from here is fat, which insulates and stores energy for the first days after birth. The brain keeps growing faster than any other organ.
The kidneys are fully developed, and the liver processes some waste. The baby is running out of room, so movement shifts from jabs to rolls and stretches. Most babies are head-down by this week.
Gestationally, week 35 means you are 34 weeks and 0 to 6 days pregnant, day 239 to day 245 counted from the first day of your last period. This is week 8 of the third trimester (weeks 28–40). Appointments step up to every two weeks from week 28. Week 36 brings weekly appointments and lightening. From here the baby gains roughly half a pound a week on average, which is why the third trimester feels measurably heavier by the day. Every number on this page is an average across pregnancies; your own scan dates and your baby's measurements are what actually describe your week 35.
Install the car seat and have it checked; most hospitals require it before discharge. Rest between errands.
Weeks of pregnancy don't map cleanly to calendar months, but the common division puts week 35 falls in month 3 of pregnancy (weeks 9–13). Week 35 is part of the third trimester, which runs from week 28 to birth. Gestationally, week 35 means you are 34 weeks and 0 to 6 days pregnant.
At week 35 the baby averages 18.2 in long and weighs about 5.25 lb, roughly the size of a honeydew melon. Sizes come from fetal growth charts (crown-to-heel length from week 20), and normal variation week to week is wide; your ultrasound measurements always outrank a chart.
