If there is brown discharge and there is pain in the small stomach with a history of menopause, it may be related to pregnancy, such as pre-eclampsia due to progesterone deficiency, brown discharge, and it can cause contraction of the smooth muscle of the uterus and tingling pain in the small stomach. It is recommended to go to the hospital as soon as possible to have blood tests for blood HCG and progesterone before the diagnosis can be confirmed. In addition, if the blood HCG shows a positive result, it is clinically necessary to exclude the possibility of ectopic pregnancy, so it is necessary to monitor the blood HCG in order to finally come up with the appropriate result and then give treatment. If this condition occurs without a history of menopause, it is most commonly caused by chronic inflammation of the pelvic cavity, and the corresponding diagnosis can be clarified through gynecological examination and ultrasound, and anti-inflammatory treatment can be actively given.
