Emergency Contraception
"I took this pill 19 hours after our condom leaked.  My period had just ended, so we wanted to be cautious.  I took it on Jan 4, 5 days later I had some abdominal cramping, a severe headache and cramping.  The bleeding and cramping lasted 4 1/2 days.  I also had some very minor light headedness off on of during January, but I&#039;m not sure if it was really caused by the pill or not.  My next period was very late, I usually have a short cycle, about 25 days since I don&#039;t use birth control pills regularly it&#039;s length is irregular, but mine came a full 7 days after my longest cycle of 28 days.  It started on Feb 2.  I did have more cramping the week before it started.  The cramping was not fun, but at least it worked."
