Can someone help me!

So I went to the doctor. Found out I have a yeast infection! Took care of that and finished everything Tuesday! My boyfriend came back in town from being gone for 2 weeks and he started to finger me and blood came out of my vagina.. Not a normal amount either. I'm not on my period or suppose to be (I'm on BC) and were sexually active so it's not my hymen! So what else could it be? I bleed for about 5 minutes last night and then throughout the day all my discharge has had a little bit of blood.. Any ideas?
