Bleeding after my boyfriend fingers me. What's going on?

Brianna

So this happens sometimes. Me and my bf will get down to it and he'll finger me. Everything feels great and there is no discomfort. I've been late for me period this month (March) but it happens even when i don't miss or be late for my period. But after a while I'll begin to have light bleeding and then it stops within 1-2 days. Does anybody know whats going on?
