Levonorgestrel
"The first day of my last cycle was on May 29th, I had sex on June 13th, a day I was fertile. We used a condom but of course it broke and that was my only form of protection, he finished inside me because we didn't realize it till after. Took the morning after pill about 16 hours later (My Way) and was stressing out because I've been told if you've already ovulated it won't work but it was worth a shot. My period came two days early. I am truly lucky! My advice to you is to take your mind off things and stop searching so many different things that only scare you more. Wait it out."
