emergency contraception
"This worked both times I took it. The first time I took it in 2014, I wasn't very nervous because I didn't ever consider tracking when I was fertile, so I didn't consider ovulation, just got my period and was happy.

The second time I took it, I was terrified. I was very fertile when my boyfriend and I had sex, (unprotected...  I know, getting the copper IUD next month). I took the pill the day after and it made me feel slightly queasy. I was moody, and it made me break out a little (I usually get some acne around the time my period starts too). The side effects lasted on and off for the entire time. I think i took the pill around August 6th, and I just got my period yesterday, August 21st. It came about 4 days late, but it works! :)"
