"the condom broke the day before i was supposed to start my period and i took plan b one-step an hour after the &#039;accident&#039;.  i was very tired and sick to my stomach but after a good nights rest (10hours, which is unusually long for me) i felt much better, the cramps felt like i was being ripped in two and were so bad they caused diarrhea.  then 5 days after taking the pill i started my period, i have never been so glad to bleed so much.  i bled for 5days and it was pretty heavy.  it worked great."
