it was my first month on the pill and on the last saturday before i started my week on placebo pills, i took my active birth control pill about 12 hours late. sunday morning, i took my placebo pill and that afternoon had sex and the condom broke. he didn't ejaculate inside me. i went to planned parenthood on monday to check to make sure that there were no pieces of condom inside of me that might cause infection. the nurse practitioner said that i was probably in the clear and not pregnant, even though i took that last pill 12 hours late. about three days into my placebo week, i had a VERY little bit of dark spotting, that only happened once during the day. it was so light that i would not at all consider it a period and did not have any other spotting the rest of the week. now i have started a new pack of pills and am on the fourth active one, but still no period. should i be worried? can i be pregnant? how long do i have to wait before i can take a pregnancy test? it has been 12 days since the intercourse. i havent had sex since.
