I am currently on the birth control pill and usually only ever cramp while I'm on my period. Last month I skipped 2 pills to get back on track and ever since I've been cramping every day. It's not all day, only at night I start cramping and it gets to the point where I curl up because I'm in so much pain. Is this normal since I skipped 2 pills? Should I still be cramping every day after a month?
