Women who have breast pain after postponing menstruation: The first situation may be that women have postponed menstruation due to work pressure, psychological effects, and the level of progesterone in the body does not retreat in time. In the second case, it is also possible that a woman has a pregnancy and will not have a period, which can lead to chest pain. Therefore, when a woman has chest pains after postponing her period, it is best to go to the hospital and do a urine pregnancy test first. The presence of two red bars is usually highly suspicious of early pregnancy, and a gynecological ultrasound is needed to confirm the diagnosis. If a red bar appears in the urine pregnancy test, the chorionic gonadotropin level in the blood is not elevated, or there is no abnormality in the uterine cavity under the gynecological ultrasound, and the thickness of the uterine endometrium is around 1.2cm, then it is necessary to give progesterone-type medication to promote menstruation or to continue to observe the period for one week to see if it is a normal menstrual flow.
