After pregnancy, women will experience changes in various aspects of their bodies, such as endocrine function and body shape. Pregnant women's hormone secretion will significantly increase, and their bodies will gain weight, with their stomachs rapidly bulging. However, the biggest change during pregnancy should be the uterus. So, what changes do the uterus undergo during the early stages of pregnancy?

When a woman is one month pregnant, the size of her uterus is similar to before pregnancy and there is not much change. However, compared to before pregnancy, the uterine wall becomes softer after pregnancy. Some pregnant women may experience symptoms of nausea and vomiting due to hormonal imbalances in their bodies. And it is also prone to symptoms similar to a cold, such as physical weakness, fever, and chills.
At 2 months of pregnancy, the uterine wall and cervix of pregnant women will become thicker, which can provide protection for the fetus. Usually between 8-12 weeks of pregnancy, the first formal prenatal examination is required, which includes basic checks such as consultation, weight measurement, blood pressure, as well as listening to fetal heart rate, urine and blood tests, and checking uterine size.
At 3 months of pregnancy, a woman's uterus looks like a grapefruit and gradually enlarges as the fetus grows. At this point, the bottom of the uterus can be reached at the pubic symphysis. An enlarged uterus can compress organs and tissues such as the bladder and rectum, leading to a decrease in bladder capacity. As a result, pregnant women may experience frequent urination and a feeling of incomplete emptying of the bladder.
