Bleeding Every Time After Sex

So my first time having sex I didn't bleed at all, which surprised both of us. But now that we go at it maybe once a week, I find that I lose a little blood each time. Last night specifically, he finished me with his hands after going at it with his dick and cuming first, but once I got off his whole hand was SOAKED in blood! And it just kept oozing all over my legs and dripping on the floor! I thought I started my period early so I put in a tampon and pad, went all day with one in, and pulled it out whiter than snow!
