I'm having a sharp scraping feeling on my right ovary lower abdomen area it doesn't feel like regular menstrual cramps I can't really describe it, it's a weird pain but I am supposed to get my period in 5 days so I'm not sure if it is because of that. I also had a small amount of stringy brown discharge that was sticky. Am I getting my period early? Is this implantation symptoms? Endometriosis? From birth control?Something else medical related? Please help
