Can anyone help me

Valerie

So this morning I woke up and I was bleeding, it was a dark brown/red color

But my period isn't due to come until beginning of December I just got done with my period

I recently had unprotected sex and he didn't cum in me, he came outside and put it back in right after. (What an idiot) so I took an emergency contraceptive pill

And I don't know what's going on
