Bleeding during sexual activities.

I've been doing sexual things for the past few months with my (first) boyfriend and I've been fingered a lot over the past 4 or so months and recently he went really fast and hard and I bled a bit which I expected because he went super fast so I assumed my hymen had broken but he fingered me on Thursday? And I stated to bleed, a lot- it went through to his mattress and dripped down my leg and went all over his carpet and he wasn't even going that hard and it didn't hurt at all so I'm not sure what happened but there was a lot of blood. And then since then it hurts to sit down in certain positions and when I pee- the left of where the pee comes out hurts but not in a stingy way just hurts and I'm not sure whats wrong?
