hi if there combination pills combination pills have two hormones — estrogen and progestin. its 7 days you need protection for ie condoms and these need to be started on the first day of your period. progestin-only pills you may start the progestin-only pill at any time. but again you need condome for 48 hours. i think a plan b would have been the way to go there a 72 hour window for them if its not to late bc pills are not an emergency pill. do hope this helps good luck ps your playing with fire having unprotected sex.
i had one unprotected sex and then started the pill the next day. how much chance i have to be pregnant? . used spermicide but when got up of the bed found half of it and took the pill the next day. is it considering unprotected sex? if so what are my chance to be pregnant and how can i know if im still on the pill.
