Weeks 28-30: Continued Growth and Preparation
During weeks 28-30, the baby's lungs are maturing rapidly, and they are practicing breathing movements in preparation for life outside the womb. The mother's body is also undergoing significant changes, including:
- Increased fetal movement: As the baby grows and becomes more active, mothers may feel more pronounced kicking, rolling, and stretching.
- Braxton Hicks contractions: Mild, practice contractions that help prepare the uterus for labor.
- Breast engorgement: Hormonal changes can cause breast tenderness and swelling.
| Fetal Development Milestones | Weeks 28-30 |
|---|---|
| Fetal Length | 15-16 inches (38-40 cm) |
| Fetal Weight | 2.5-3.5 pounds (1.1-1.6 kg) |
Weeks 31-34: Physical Changes and Preparations
As the pregnancy advances, the mother's body undergoes further transformations:
Pelvic pressure and back pain are common complaints during this period, as the baby's head begins to descend into the pelvis. Other notable changes include:
- Shortness of breath: The growing uterus can put pressure on the diaphragm, making it harder to breathe.
- Leg swelling and varicose veins: Fluid retention and increased blood volume can cause swelling and vein visibility.
- Nausea and heartburn: Hormonal fluctuations and pressure on the stomach can lead to digestive issues.
