So i have been on birth control since August 2010. In april i got my withdrawal period on the 5-8th. I then started my new pack of birth control on the 10th i forgot to take it on wednesday the 13th-15th and started another withdrawal period. through the 15-18th. I had unprotected sex on the 18th and i didnt start my birth control because i was confused on what to do. I have been off birth control since ive missed my pills. I was getting real bad cramps last week to this week. I never get cramps even when i wasnt on birth control so i am kinda scared. My question is around when would i ovulate and when should i expect to start my period!?!?
