emergency contraception
"Had unprotected sex right in the middle of my cycle.  Took this roughly 24 hours after having sex.   I felt pretty emotional for a few days afterwards.  Not sure if that was from the pill or the situation I put myself in.   Anyway, for about a week and a half I felt nauseous, had cramps, was very tired and had headaches.   I also started spotting about 2 weeks after taking it.   I thought I was starting my period.  However my actual period was delayed a couple days.  Very happy this product exists!  I will not put myself in the situation to have to use it again, however."
