Third Trimester Timeline

The third trimester typically starts around the 28th week of pregnancy and lasts until birth, which usually occurs between 38 and 42 weeks of gestation. This trimester is divided into three months, with each month marking significant milestones in fetal development and preparation for childbirth. The 28th to 30th weeks are critical for fetal brain and nervous system development, while the 31st to 33rd weeks see the baby's lungs starting to produce surfactant, a substance that helps them expand and contract properly after birth.

During this period, the fetus continues to grow and develop, and the mother's body starts to prepare for childbirth. The baby's brain and nervous system are maturing, and their senses are becoming more refined.

Month 8: Weeks 31-34

The 31st to 34th weeks are a critical period for fetal development, with the baby's lungs starting to produce surfactant and their digestive system practicing contractions to prepare for life outside the womb.
