When Is 2Nd Trimester

The second trimester of pregnancy, also known as the middle trimester, typically begins around the 13th week of gestation and lasts until the 26th week. This period is crucial for the development of the fetus, and it’s also a time when many women start to feel more comfortable and confident in their pregnancy.

During the second trimester, the fetus continues to grow and develop at a rapid pace. Its major organs and body systems start to function, and its senses begin to develop. The fetus can swallow, kick, and even suck its thumb. Its skin starts to thicken, and fat layers form, helping to regulate body temperature.

For the mother, the second trimester often brings a sense of relief from the early pregnancy symptoms such as morning sickness and fatigue. Many women experience a surge in energy levels and start to feel more like themselves. The baby bump becomes more noticeable, and the mother may start to feel the baby’s movements, such as kicking and rolling.
