period sex‼️

So i had period sex for the first time and now my bleeding is just 10x worse like the morning after i woke up to go pee and it was just a river of blood and so i thought maybe jt’s just my period and not bc i did it on my period but then i had period sex again that night and its really bad and i have to change my pad like a lot now bc of how much i bleed. I just don’t know what’s going on...can someone please explain?😩
