"i am 22 and not on birth control currently for neurological reasons.

a day or two after my period ended (sunday, oct 18), i had sex with a condom. the condom broke and we did not notice until we were finished. we went and got the pill and i took it within an hour of the unprotected sex. the next day i was mildly fatigued and had some mild cramping for a few days, but no side effects other than that. exactly one week later, october 25th, i began bleeding. this is considered withdrawal bleeding from the pill. exactly four weeks after the withdrawal bleeding begun, i got my period! i suggest taking a pregnancy test any time you worry about it, but know your period can be late from it&#039;s normal time because of the pill. it works!"
