really really painful please give advice

so i’m on the pill and i am up to the sugar pills and my period has been so painful it’s hard to walk and sit down and it’s a very sharp pain just above my pubic bone it feels like i’m gonna collapse or throw up, it also gets worse when i eat. should i just stop the sugar pills early and start the new packet early? (i’ve been on the pill for a month this is my first time and i’m only 14, i’m using it to prevent pregnancy not cramps)
