Every month i used to mensturate on 19th or 20th day and they were 5 days duration and regular. Last month my LMP is 20.3.2015. I have unprotected sex with my boyfriend and take EC pills on 28th March. Then, my period starts on 31st March. As usual, it was 5 days duration! Then, i had sex again with my boyfriend on 13th april 2015 and take EC pills on that night!
On 14th,15th,16th and17th days, we had sex but he didn't ejaculate and i didn't take EC pills. But i took it on 19th day coz i worried for pregnancy!
I wanna know that my EC pills will be effective? About how many percentage failure rate?
Plz help me
