The second trimester of pregnancy, spanning from weeks 13 to 26, is often referred to as the "golden period" of pregnancy. This phase is characterized by a significant decrease in morning sickness and fatigue, allowing many women to enjoy a renewed sense of energy and well-being. As your body continues to undergo changes, it's essential to understand what to expect during this critical period of fetal development.
During the second trimester, your baby grows rapidly, and their major organs and body systems begin to function. This is an exciting time, and many women start to feel a sense of connection with their unborn child. As you approach the midpoint of your pregnancy, you may have questions about what to expect and how to navigate this period. In this article, we'll explore the physical and emotional changes you may experience during the second trimester, as well as provide guidance on fetal development, nutrition, and preparation for motherhood.
Physical Changes During the Second Trimester
As you enter the second trimester, you may notice a range of physical changes. Your uterus has expanded to the size of a small melon, and you may start to feel a slight bulge in your lower abdomen. Your baby bump may become more pronounced, and you may need to adjust your wardrobe to accommodate your growing belly.
Baby Bump and Body Changes
During this period, your body undergoes significant changes to support your growing fetus. Your skin may stretch, and you may experience striae, also known as stretch marks. These marks are a normal part of pregnancy and may appear on your abdomen, breasts, and thighs. Additionally, you may experience linea nigra, a dark line that runs from your navel to your pubic bone.
