Tmi, but I need help

Tory

So after not having my period for a month or two, it's here and it's terrible. Like I'm changing my tampon every hour and wearing pads. I have horrible cramps because of it. My periods have never been like this and I want to cry. Is there anything I can do to help with cramps? Heat is doing nothing. I have a muscle relaxer and thought maybe that would help but it didn't. I don't know what to do. I can't sleep because of the pain
