when is the third trimester of pregnancy

The third trimester of pregnancy begins at week 28 and lasts until the end of the pregnancy, typically around week 40 or until the baby is born. It covers roughly the final three months of pregnancy. During this trimester, the fetus gains weight rapidly, and its organs mature in preparation for birth. It is also a time when pregnant people may experience new symptoms such as shortness of breath and false contractions. Prenatal visits become more frequent during this period to closely monitor the health of both the parent and baby.
