emergency contraception
"I took this approximately 48 hours after unprotected sex while I was ovulating.  I felt fine after taking the pill. A few days before my period was due I experienced major mood swings, bloating, cramps and sore breasts. These symptoms  lasted the few days before I was due and then the symptoms stopped on the actual day I was due. But no period. Needless to say I was freaking out! (This is why I am writing this to help others from freaking) -- I was supposed to start on a Friday. Then Saturday rolls around, then Sunday and no period... Just really, really sore breasts on Sunday. That Monday evening I finally started and had breast tenderness, cramps, headache, tiredness... But atleast I started - 3 (longest days of my life) days late."
