TMI after sex

Samantha
Has anyone experienced getting their 'cherry' popped twice? The first time, about 1 1/2 years ago, I had sex (the whole 2 minutes) my cherry popped. However, my boyfriend and I just had sex together for the first time and now I think he bruised my cervix or popped my cherry again. We were completely safe; condom, the after pill even though he did not cum during sex, everything. I have had brown, membrane-like discharge for the past 4 days since. Please help! What is this? Should I be worried?
