Women who experience delayed menstruation, breast tenderness and abdominal pain may have symptoms caused by pregnancy. Because the progesterone in a woman’s body increases rapidly after pregnancy, it can lead to symptoms of breast swelling and pain. As the uterus increases in size after pregnancy, it will compress the tissues around the pelvic area, thus causing pain in the abdomen. It may also be a symptom that a woman is about to get her period, because when a woman is about to get her period, the level of estrogen and progesterone secretion in her body will change, so she will also experience breast pain and abdominal pain. If a woman usually has a regular period and has a normal sexual life, if the above symptoms occur, you should rule out the possibility of early pregnancy and go to the hospital for an early pregnancy test. If you are not pregnant, it is possible that you are about to have your period, so just be patient and wait.
