Third Trimester: Weeks 28 Through 40
During the third trimester of pregnancy, which spans from weeks 28 to 40, expectant mothers may experience various physical changes. One common symptom is swelling, particularly in the feet, ankles, hands, and even the face. This swelling occurs because the growing baby is exerting more pressure on the mother’s organs.
As the baby continues to grow, the mother may also experience shortness of breath and a more frequent urge to urinate. Leg cramps are another common complaint during this stage. Additionally, some women may find it difficult to sleep due to disturbances such as discomfort or increased bathroom trips.
Another noticeable change during the third trimester is the leakage of colostrum from the breasts. Colostrum is a thin, watery fluid that serves as the precursor to breast milk.
Throughout the third trimester, obstetricians closely monitor the mother’s blood pressure, weight, and urine. They may also increase the frequency of prenatal visits to ensure the well-being of both mother and baby.
Some expectant mothers may experience Braxton-Hicks contractions more frequently during this stage. However, it is important to note that not all women will encounter these practice contractions.
Fetal Development: The Exciting Progress in the Third Trimester
During the third trimester, the remarkable development of the fetus continues to unfold. By this stage, the fetus has not only acquired the ability to see and hear, but also demonstrates newfound skills such as sucking its thumb and crying. A protective layer known as vernix envelops the entire body, ensuring its safety. As the weeks progress, the bones grow stronger, although the skull remains soft to facilitate a smoother journey through the birth canal. Around week 36, the baby’s head may descend into the pelvic area, a process commonly referred to as “lightening.” As the third trimester draws to a close, the average weight of the fetus ranges from six to nine pounds, with a length of 19 to 21 inches.
