"i said i would do this if it worked and it did. when i took plan b, it was a day after my period had ended and i knew i was going to be fertile. i took it about 10 hours later and i didn&#039;t feel any symptoms. i got my period again 7 days later. i normally have cramps and all that but it was just huge clots and heavy for 5 days, which is shorter than my period. i didn&#039;t know if that counted as my real period since it was 3 weeks early, but i got a second period when my normal period was due, only 2 days late. i was so nervous the whole time. i had tender breasts, i was nauseous and i had cramps a week before my period, but worse than they normally are. my second period after that was 3 days late. plan b messed up your body a ton! just pray!!"
