So I'm on birth control & have been for 6 - 7 months now. I came on my period on the 4th and ended the 10th or 11th. I had unprotected sex on Friday, and yesterday there were very faint pinkish spots & today I'm bleeding a lot more, but its more brown than red. I've been told that sex makes your period come faster or that it could have torn really easily, and I haven't had sex in almost 6 months so this was a first in a long time. pleaaaasseeee help
