emergency contraception
"me and my boyfriend had unprotected sex on the last day of my period. I knew the chances of getting pregnant on the last day of your period are slim but I didn't want to take any chances. Therefore 30 minutes after I went ahead and bought plan B. The only side affect I experienced at first was a slim headache and it only lasted the first day. The pill also messed with my hormones and I had a huge break out on my face. The closer I got to my period I stated stressing more and the pill delayed my period by 6 days. So if you already took the pill and you're late don't worry it's the pill doing its job."
