OMG after reading all that Im freaked out. Ok heres the deal I used to be on the BC Shot but i was off of it for 10 days which was when my appointment was. the day of my appointment friday i was switched to the pill again and i got it filled saturday and took it dat night and the next morning. then sunday afternoon me and my boyfriend had sex which he used a condom. I need to no if I should be worried and if my BC is working and if not if i could be pregnant even though he used a condom
