I took a unwanted 72 pill within 1 day after doing unprotected sex & i also bleed it out in 7 d. but from 1 and half months (1.5 months) my periods didn't came .i also test for pregnancy by pregnancy kit test 2 times in morning but there were no sign?

About those pills...: Emergency contraception pills are hormones and alter one's menstrual period bleeding for that month and maybe the month after. One can take a urine pregnancy test (follow instructions on the package) 3 weeks after sex to confirm non-pregnancy. If test result is negative but she is still worried, or if her next period doesn't look or seem normal, she can repeat a pregnancy test one more time.
