HELP!!!

So my period just started..... and first of all I haven been on birth control for a month because my doctor was being difficult and I just got my new proscription but I can’t start it until the Sunday after my period started which luckily is in a couple days, but I went on the pill to help regulate my body so I was terrified knowing what was to come this month and I was right..... it’s only my first day I use super plus tampons and I have to change it every hour or so and the cramps are horrible I can’t eat because I feel sick and my old remedies don’t work. Does anyone have any suggestions? I’m honestly feeling like I’m gonna bleed too much
