please help!

I just started my birth control this month, on the Sunday after my period. I took the pill some/what consistently for two weeks. I started cramping really badly yesterday and when that started I immediately took two birth control pills. I have always had easy periods, but this has been the most painful period by far. I've been e perinecinv very sharp pains in my vagina and stomach. Is this normal? I don't know what's wrong with me and I'm scared to go to the doctor!
