Tmi maybe but my bf and I just had sex.. And

There was blood, not gushing but, plenty. But not just spotting. When I cleaned off, I wiped and it was just blood. And its still kind of coming cause I wiped again about twice more and went a little deeper, i know that sounds gross but I didn't shove my finger up there lol, but anyway went a little deeper and there was still a little blood when I wiped. So

1. Its coming from the inside

2. This has never happened before

3. I just got off my period like a week ago, and oddly enough my period was wacky. I had two in one a one month span. And I haven't had any weird spotting since..

Any ideas
