Introduction
Week 21 of pregnancy marks a significant milestone in the journey of motherhood. By this time, the fetus has grown substantially and is developing rapidly. This article provides a comprehensive guide to the physical, emotional, and medical aspects of week 21 of pregnancy, empowering expectant mothers with essential information and insights.
Physical Changes
- Uterus Expansion: The uterus continues to expand rapidly, reaching the level of the belly button. This can cause increased abdominal pressure and discomfort.
- Weight Gain: Most women gain between 10-15 pounds by week 21. This weight gain is primarily due to the growing fetus, placenta, and increased blood volume.
- Skin Changes: Darkening of the skin around the nipples (areolae) and a line running from the belly button to the pubic bone (linea nigra) may become more pronounced.
- Varicose Veins: Increased blood flow can lead to the development of varicose veins, especially in the legs.
- Constipation: Hormonal changes and the pressure of the expanding uterus can slow down digestion, leading to constipation.
Fetal Development
- Size and Weight: The fetus is approximately 10 inches long and weighs about 13 ounces.
