question: I was on a birth control pill for about a month. It was causing me to be very moody, and have awful cramps. So i stopped, but i stopped in the middle of a pack. There was 3 weeks of hormone pills, then one week of substitute pills. I ttook one month of pills had my period, I took one weak of hormone pills then stopped. I had a period about a week after I stopped. My period normally comes on the 1 of every month. I stopped last month, it is now december and the first has passed and then the date of my withdrawal bleed had passed. I have not had a period.Could the birth control have messed with my cycle that badly, or could i be pregnant?
