In the early stages of pregnancy, due to the possible exuberance of progesterone in the body, it will stimulate the expansion of the blood vessels in the breasts, causing them to develop for the second time, and you may feel more pain when touching them. In this case, it is recommended to wear loose underwear and not to over-stimulate the nipples, so as not to cause mild uterine contractions, which may cause abdominal pain or even bleeding. If necessary, local hot compresses can be applied to relieve the pain, which may slowly ease after 3 months of pregnancy, and some people will slowly return to normal after 1 month or even 2 months of pregnancy, which will not affect their health. Pay attention to good personal hygiene, including vulva hygiene, to avoid causing cross-infection, and pay attention to the various examinations during pregnancy to ensure the stability and health of the fetus.
