Hello, my girlfriend is going through a rather odd experience. She previously had an ovarian cyst a couple of years ago now. She just finished her period about 2 weeks ago, and is now heavily bleeding again, constantly for about 4/5 hours, it hurts her to urinate and bad cramps. The bleeding has now stopped, and cramps have subsided. Sexual intercourse hasn t occurred since her last period and she is 18 years of age and is on birth control. Is this something to be concerned of, thanks.
