emergency contraception
"I had  sex with my boyfriend the same day as I ovulated. I knew I was ovulating by the date and by observation. I keep track of my period and ovulation religiously. He did not pull out and went inside of me. I bought the plan b pill about 20 hours after the accident. The only side effect that I experienced was minor cramping 7 days after taking the pill and my breast were a little swollen. I started one day early and experienced little cramping. I was terrified that I was going to have horrible cramps from the reviews that I have read. Not the case for me!!! I definitely recommend plan b if you suspect that you may be pregnant."
