Bleeding during sex and stings to pee

💙💙💙

So I just had sex and started bleeding pretty heavily during it, Ive had a bit of break through bleeding lately as I'm on the pill but it had gone before I did it, so I'm wondering, could it have been my period coming or did he tear something inside of me? It really stung to pee after as well which is why I'm thinking it was a tear.
