Last month i had my period on Sep. 9 the same month on the 23 i started birth control for the first time i have taken the pills all at the same time everyday and have not missed any. My period before i took the pill was calculated to come Oct. 10 i am now on rhe inactive pills i am suppose to take the second pill today but i still have not gotten my period i had sex on the sixth day of using the pill and again a week later both times we used a condom and both times the condom did not rip and was still in good condition. Could i be prwgnant or why have i not gotten my period?
