My boyfriend and I had sex on Saturday, and it was not until he pulled out that we realized the condom had a tear it in. Not by much, but enough that some may have gotten inside. Seven hours after it happened, I began taking Next Choice. My period was supposed to come this week, today, Wednesday, and it has not come. I have also had no side effects either. Does this mean that the medication has not worked yet? Also, how long can your period be delayed? Since my period was so close to the time of the accident, I don't believe I was fertile at all so that's one positive. I know it has only been 3 days since taking next choice, but I'd just like to be certain that everything is going to be okay.
