Levonorgestrel
"It works! Me and my husband stay in different cities and were meeting after 3 whole months. We were so into it that we didn't bother to get the condom lying in the closet. He thought he would pull it out at the correct time but he couldn't. I was terrified. My period was due in a week. I spent the night contemplating whether it was safe to take the pill because I never took it before. But we were not ready for a baby and so I took it the next morning, after almost 12hrs. I didn't experience any side effects as given on the package. My period got delayed by 3 days and finally got it yesterday. It's great so chill! Easy to say this now but those 3 days were hell. Better be safe!"
