If the symptoms of breast swelling and pain in early pregnancy suddenly disappear, you need to go to the hospital for an ultrasound examination to check the development of the fetus in the uterine cavity, if the fetus is developing normally, there is no need to worry. Because breast pain in early pregnancy is a normal physiological phenomenon caused by the increase of hormones in the body after pregnancy, but with the development of the fetus after the stabilization of hormone levels in the body, breast pain will reduce or disappear. The breast pain will disappear in 2-3 months after pregnancy, but if there is a miscarriage, stillbirth, etc. will also cause the body’s hormone levels to drop, which will make the breast pain disappear, so you need to go to the hospital for an obstetrical examination if there is a miscarriage aura will cause abdominal pain, bleeding, you need to take timely birth control drugs such as progesterone, vitamin E, etc.. If a stillbirth occurs, it is best to have an abortion in time to avoid intrauterine infection caused by the embryo staying in the uterus for too long.
