The second trimester of pregnancy is often regarded as the most enjoyable phase, as many women experience a decrease in nausea and an increase in energy. Understanding the week by week second trimester is essential for expecting parents to prepare for the significant developments happening within their bodies and their growing baby. This post provides an in-depth guide to what happens each week during the second trimester, along with practical tips for managing physical and emotional changes.
Introduction
The second trimester spans from weeks 13 to 27 of pregnancy and is a time of rapid growth and development for the fetus. During this period, many mothers find that their symptoms from the first trimester, such as morning sickness and fatigue, may start to diminish. However, new experiences and challenges arise as the body adapts to accommodate the growing baby.
