hi I'm an 18 yr old female and on Monday the 19th my boyfriend and I were messing around. he fingered me and I noticed that I bled and then on Friday I started feeling these mild cramps and my period isn't due for 2 weeks we had sex on the 25th and when I used the bathroom I noticed I was bleeding it wasn't much blood though I don't know what's happening this is the first time any if this has happened and the cramps won't go away it's been 4 days.
