Hi, I have a question about starting birth control late. I was supposed to start my birth control on Sunday July 9th but was unable to start until Sunday July 16th. Now I have 4 pills left and I still haven't started my period. Had sex the week I was off birth control but used protection. Anyways, I am now almost 2 weeks late for my period. Regular symptoms of starting birth control a week late or could this be pregnancy?
