Levonorgestrel
"I was having sex with my boyfriend and somewhere in the mist of it all out condom broke . We started to freak and regret all our life decisions. I took the pill about an hour and a half later and began to immediately feel tired afterwards . It lasted for about two days along with bad mood swings , frequent head aches ..nothing to bad..and a few cramps here and there . despite all the side affects, waiting is definitely the worst part. When I didn't get my period on the day I was supposed to I began to panic . I even went out and bought pregnancy test that came back negative . Sure enough today , my period came, 3 days late . I have never been so happy to see blood in my entire life . This pill is a life saver !!"
