Slight bleeding during sex?

Last night halfway through sex my boyfriend pulled away and said "what's on your arm?" I look and see two bloody fingerprints from him. Previously he had been fingering me. Obvious signs point to a bloody vagina. But I'm not due for my period for another 14 days.

I go to the bathroom and wipe to see how much comes up. Only one swipe got all of it and then I was completely dry. Including up my vaginal canal. We continued to have sex later that night and I didn't bleed again.

Now I'm having a lot of thick white discharge. It's not cottage-cheesy. I'm just a little confused. Any ideas what could be going on?
