Thanks for your question. It sounds like you should speak with your doctor
about this question, as there are many possible explanations for abnormal vaginal discharge, which is most often consistent with bleeding
. Given that there are so many different things that could be the cause, and some of them are serious, your doctor or OB will best be able to help. Some of the reasons for this could be simple things such as minor trauma or changes in your menstrual cycle due to stress or nutrition. Other possible explanations involve your birth control
. Other possibilities include tumors that can occur anywhere in the vagina or uterus. Some of these can be common and benign, such as fibroids, while others can be more serious and require significant medical attention. There are other changes as well that can happen to the mucosal lining of the vagina or cervix and increase the amount of vaginal bleeding, and some of these can also be serious. With regards to why your stomach hurts, it could certainly have something to do with menstruation as many women will have cramps that can be quite painful. Your doctor should be able to help you understand the cause, and ask further questions, so please speak with your doctor.
