Weird Period Symtoms?

M

When I’m on my period I always feel TERRIBLE. I have terrible cramps, the worst hot flashes ever and start sweating, then I get extremely cold. Sometimes I get a fever also. I can’t imagine that’s normal. It’s happened consistently enough I know it has to be related, because it only happens when I’m on my period. I also have very heavy periods, if that matters. I’m 17.

Any advice on what to do??
