Emergency Contraception
"I want to share my experience to possibly ease some of the ladies out there.
The incident occur in Nov 18 (the condom broke) and it was 4 days after my period ended and approximately 4 days before ovulation. This means I was fertile. 
when we noticed that the condom broke, we immediately bought Plan B One Step and was taken about 45 minutes or an hour later. 
The sooner you take the greater the chances it will work.
So I waited anxiously, praying I get my period. I felt side effects such as fatigue, bloated, nauseous, cramps, and moody. I was that these might be  this pregnancy symptoms. 
I waited exactly two weeks and I got my period. I was the happiest person ever. My period was here early by approximately 3-4 days. Good luck."
