35 weeks pregnant
At 35 weeks you are in the third trimester, and your baby measures about 46 cm from head to heel and weighs about 2.4 kg, roughly the length of a small watermelon. The group B strep swab window opens this week and runs to 37 weeks, and the car seat should be fitted before 37 weeks.
Weighs about 2.4 kg, like a bag of oranges. Averages from standard growth tables; your scan gives your baby's own numbers.
