So my period isn’t due until the 4th but i am cramping so bad. And I have been on the toilet all morning. I had been on birth control from the time I was 16-19 then I had my son then again from 20-22 so my periods were a little weird. Since I got my birth control my periods have came every month on the 4th with no symptoms until after my period then I cramp and break out. So now I’m cramping hard as hell way early. I guess what I’m wondering is has anyone else had a normal period, then it switch up on you down the road?
