"don&#039;t even bother stressing yourself out like i did, because plan b actually works. on june 25th i had unprotected sex with my bf and on that day i was ovulating and my bf wasn&#039;t wearing condoms and i wasn&#039;t on birth control pills. i know this is tmi, but he &quot;came&quot;/finished inside me. so, 2 hours later i started to get paranoid and decided to take plan b. well let me tell you this i received so many pregnancy symptoms such as: sore breast, headaches, fatigue, nausea/vomiting, frequent urination,back pains, and cramping. the side effects will have you going insane. the scary part is that a week before my period was due i saw brown discharge and i automatically assumed that it was implantation bleeding. next following week my period came."
