I did not take my birth control very well this month. I had a period then half way in I missed a few pills and had some spot bleeding.. I forgot to take them for the last 4 days. I did not have any bleeding during the week off of pills. I have since started a new pack. I am have some really bad stomach pains and cramping. I have not had sex since my last period. (July 1st).. Could I be pregnant... Or are my hormones messed up?
