Intro
Discover what to expect during the 3rd trimester, starting at week 28, with symptoms, fetal development, and pregnancy care tips, ensuring a healthy birth and postpartum experience.
The third trimester of pregnancy is a critical period of growth and development for the fetus, and it is essential for expectant mothers to understand the changes that occur during this time. The third trimester starts at week 28 of pregnancy and lasts until birth, which typically occurs between 38 and 42 weeks. During this period, the fetus will continue to grow and develop, and the mother's body will undergo significant changes to prepare for childbirth.
As the third trimester begins, the fetus is approximately 15 inches long and weighs around 2 pounds. Despite its small size, the fetus is fully formed and has all the necessary organs and body parts.

The fetus's lungs are also maturing, and it is starting to practice breathing movements, which are essential for life outside the womb.

As the fetus grows, the mother's belly will expand, and she may experience a range of symptoms, including back pain, pelvic pressure, and fatigue. The mother's body is also preparing for childbirth, and her cervix is starting to dilate and efface, which will help the baby to pass through the birth canal during delivery. The mother's hormones are also changing, and she may experience mood swings, anxiety, and excitement as she prepares for the arrival of her baby.
