emergency contraception
"I just wanted to share my experience with the skipped period side effect that can happen with this pill. I have taken Plan b twice before this last time and had experienced no side effects those times. This time I took it the day after my period ended, When it came time for my next period to start there was nothing. I searched online and it seemed a lot of people posted about skipped period but never followed up to say if they got there period or not. I took 3 pregnancy test and all came back negative. I skipped 1 whole period and then the next month my period came right on time. So if you experience this same effect and your test come back negative, dont panic. See your doctor if you have to or just wait for your body to get back on track"
