emergency contraception
"Took a plan b about 1 hour after unprotected sex. About 15 minutes after taking it I had cramps not sure if it had anything to do with the pill. I read reviews about how women said that after taking plan b their periods changed drastically and they bled heavier and for more days. Usually my periods last 4 days and I'm a light bleeder. I got my period last week and nothing changed. Very positive experience for me."
