i had unprotected sex with my husband on 26th april night but with in 24 hours i took an i-pill. that month i got my periods in scheduled time, i.e.,on 18th may and it last of 5days.i have a cycle of 28-days and i usually have very normal periods. But this month i.e.,june,my periods got delayed by 9 days already,its 27th june and i didnot get my periods yet.I AM VERY SCARED. is it possible that i may get pregnant? is it the side effect of the ipill? if its a side effect then will it have an adverse effect on my reproductory system or may cause infertility or something complicated like this?
