Third Trimester of Pregnancy ─ Week by Week Symptoms and Fetus Development

Welcome to your third trimester (weeks 26-40) and the home stretch of your pregnancy! Fetus growth continues during the third trimester of your pregnancy and your week by week symptoms will vary greatly. Your baby will open his or her eyes, gain more weight, and complete essential development for life outside the womb, all this while you prepare mentally and physically for delivery.

As your baby continues to grow in the third trimester, it’s important to keep an eye on your and your baby’s health. You can continue to be active during the last few months even though your body may be slowing down naturally. Walking is a recommended exercise during this time. Additionally, its important in the third trimester to sleep on your side at night as well as during day time naps.
