"had drunk unprotected sex with my boyfriend on july 3rd. freaking out we drove to a walgreens and he bought me plan b took it within 5 hours after intercourse. i did actually ovulate a couple days before having intercourse so i thought it wasn&#039;t going to work. the first couple nights i felt very fatigue, to be honest i was also very nauseous. after a week i developed sore breasts and mild cramping today july 16th i woke up with my period, thank god! guys use protection always. if you can withstand a bit of nausea and fatigue this works wonders."
