"ladies, let me tell you my experience. so on may 25th i had unprotected sex while i was fertile according to my period tracker (i know dumb right) but he did pull out, but still i was sacred, so i rushed after to get the plan b pill at walgreens and it ran me about $50 which is expensive but it worked. so i took the pill and i felt fine for a few hours then the fatigue started to kick in. i was so sacred like you guys are reading the internet, crying just and emotional break down. i am only 20 years old and i do not want kids now. i had a lot of side effects which were fatigue, extremely bloating, nausea &amp; loss of appetite. but finally my period came 4 days early and i couldn&#039;t be so happy. just relax your period will come."
