It is relatively normal for your breasts to not swell and hurt after seven weeks of pregnancy. The swelling and pain in your breasts at the beginning of pregnancy is mainly due to hormonal changes in your body. As the weeks of pregnancy increase, the hormones in the body gradually change, especially the estrogen and progesterone levels change dramatically, so the symptoms will be relieved and there is no need to worry too much. During pregnancy, you need to pay attention to the presence of abdominal pain, irregular vaginal bleeding and other conditions to prevent miscarriage and other accidents. During pregnancy, you should pay attention to rest, avoid overworking and staying up late, and enhance the intake of nutrients, especially high-quality protein, to avoid malnutrition, which may affect the growth and development of the fetus. Avoid exposure to toxic and harmful substances, and pay attention to regular prenatal checkups to understand the growth and development of the fetus. Take folic acid on time to avoid neural tube defects in the fetus.
