If every time you have your period it is a little bit and clears up afterward, it can be clinically diagnosed as menorrhagia. There are many causes of menorrhagia, such as polycystic ovary syndrome, ovarian failure, or adhesions in the uterine cavity due to damage to the uterine lining, all of which can lead to this symptom. It is recommended that a comprehensive analysis of the clinical history and laboratory tests be combined with treatment, and most menstruation can be restored to a normal state. If menstrual dribbling occurs only once in a while, it is important to be alert to the possibility that the condition is caused by pregnancy. If there is progesterone deficiency or miscarriage after pregnancy, vaginal bleeding will occur, and ectopic pregnancy will also cause bleeding, it is recommended to go to the hospital as soon as possible for examination and treatment as soon as possible.
