It stings down there

I had sex for the first time. And he didn't know, he went really hard and fast. Afterward I realised I was bleeding thought he kick started my period. Cause I have he implant. I was cleaning the mess down there and it stung extremely painfully. And even more when I use the restroom to pee. Help I don't know want wrong and my mum has no clue!
