Patient: I am 18. i have been on the birth control pill for 2 months now. on my second pack, i got a bladder infection and was put on antibiotics. about a week later my boyfriend and i attempted sex for the first time, with a condom. it was too painful and we had to stop. i then, confused my pills and took two pills instead of one on one occasion. i am now due my period and haven’t come on. could i be pregnant?
