"success - promised myself that i would come back &amp; write a review of my experience so here we go. first time having sex and it was the day after my period ended &amp; didn&#039;t use a condom so i took plan b about 12 hours later. i&#039;ve always had a super irregular period so for the next almost 2 months (yes,2) i had anxiety every hour of the day about being pregnant. i would wake up feeling nauseous, have back pain, heartburn, and always felt bloated. personally i think that i was making myself feel that way bc i had so much anxiety. anyways, plan b does work. i&#039;m sitting heer right now chillin on my period and super happy about it. like you, i read this website and many others over and over trying to calm myself down. but you will be fine!!!!"
