The first trimester refers to the stage before 12 weeks of pregnancy, which is also the stage of fastest fetal development. At this stage, pregnant women may experience early pregnancy reactions, such as nausea, vomiting, breast tenderness, etc. At this point, the embryo has formed its organs and tissues and is beginning to develop into a fetus.
The second trimester refers to the period between 13 weeks and 27 weeks of pregnancy. During this stage, the mother\’s body gradually adapts to the pregnancy, and the fetus\’ organs and systems further develop and mature. Pregnant women may feel more energy and comfort and no longer experience early pregnancy symptoms.
The third trimester refers to the period between 28 weeks of pregnancy and delivery. During this stage, the fetus is growing rapidly and the mother\’s body is undergoing more changes. Pregnant women may experience fatigue, heartburn, edema, and increased fetal movements. In addition, pregnant women may also experience pre-delivery contraction exercises and other pre-delivery preparations.
First trimester, second trimester, and third trimester: key periods for understanding the changes in a pregnant woman’s body:
The first trimester refers to the period from conception to 12 weeks of pregnancy. During this stage, a pregnant woman\’s body goes through many changes. The most obvious thing is that pregnant women may experience early pregnancy reactions, such as nausea, vomiting, breast tenderness, etc. Additionally, pregnant women may gain some weight as the fetus begins to develop and the uterus expands.
The second trimester refers to the period from 13 weeks to 27 weeks of pregnancy. At this stage, the physical changes of pregnant women gradually decrease, and early pregnancy reactions will gradually reduce or disappear. A pregnant woman\’s uterus begins to rise, which may put pressure on the bladder, causing frequent urination. Pregnant women\’s breasts also continue to enlarge, and the areolas and nipples may become darker.
The third trimester of pregnancy refers to the period from 28 weeks of pregnancy to delivery. At this stage, the physical changes of pregnant women are more obvious. The uterus continues to enlarge, which may cause back pain and abdominal discomfort. Pregnant women may continue to gain weight as their fetus continues to grow. Additionally, pregnant women may experience shortness of breath because the uterus is putting pressure on the lungs.
It is very important for pregnant women to understand the changes in the body during these critical periods. This can help pregnant women better cope with body changes and take appropriate measures in a timely manner to stay healthy. In addition, pregnant women should also have regular prenatal check-ups to ensure the healthy development of the fetus.
