You may have chest pains in early pregnancy. Breast pain in early pregnancy is usually caused by hormonal changes, which is a normal phenomenon. In general, around 8 weeks of pregnancy, the hormone level in the body increases, and under the effect of estrogen and progesterone, the pregnant woman’s breast follicles and lobules proliferate and develop, and her breasts will slowly increase in size to prepare for breastfeeding after delivery. During this period, pregnant women may feel mild breast swelling and nipple pain. Breast pain in early pregnancy is generally more common in people who are pregnant for the first time. If you are suffering from breast enlargement, the breast pain may be relatively more severe. However, it is a physiological phenomenon that usually relieves itself in 3-4 months of pregnancy and does not require special treatment. Pregnant women can use loose underwear to reduce the external pressure on their breasts, while eating less oily food, avoiding staying up late, and avoiding stimulating the nipples. If the symptoms persist or the pain is unbearable, it is recommended to visit a hospital breast surgery department.
