ive been on the pill for about 3 weeks. i started it on the 1st day of my last period. the doctor said my period should stop when i started taking the white pills, but it didn't. and yesterday, i had unprotected sex, but used spermicide and the pull out method both times me and my boyfriend had sex. I'm a worrier and now i would like some advice from anyone with a similar experience or knowledge. scared of getting pregnant... :/
