"around may 28th (in my fertile window i believe, i track periods.) i had gone to see my boyfriend and we never really use condoms and i just started my birth control mid-cycle, so about 10 days in. i took the pill for 4 days but i wasn&#039;t aware that you had to wait at least a week for it to be effective so when i found this out about 8hrs after having unprotected sex (three rounds using the pullout method but precum contains sperm i think.) i got the ec. my period wasn&#039;t for another two weeks and all i did was panic, worry and read these reviews. since i continued taking my birth control as instructed my period came 3 days late when i started taking the placebo pill. please be safe and have protected sex.and take the pill within good time!"
