I really need help with my period cramps I've become super nauseous have a hard time controlling myself today I actually threw up and I start sweating very Hard and I am constipated when this happens. This only happens on my second day of being on my period. I really need help because I don't know what to do I'm 16 and this has been going on a lot and every time this happens I get suicidal because it hurts so bad I just want to end it and please help!
