I had unprotected sex a couple of days before i started birth control and my doctor advised me to take the morning after pill the day after and the day after that to start birth control (the pill) I started it before my period and she said it was okay, I got my period during the pill August 3 to aug 17. When i finished the pack of pills, i took the brown ones and got my period again and it started on august 19-22, because of this i am confused abt my ovulation and when i am fertile, i had un protected sex last night and 2 nights ago as well.. is there a chance I could be pregnant? I dont know when i will ovulate of if i did already, and will I get my period this month?
