"i bet all of you who are now on this blog freaking out like i did couple weeks ago. well let&#039;s cut to the chase, it worked on me. me and my boyfriend got very passionate that day and no condoms where involved. had sex twice with him. we didn&#039;t panic, even if we had a baby on a way we where ready for it.(but don&#039;t risk it if you not ready) but anyways we went out that day i ate good and went to store to buy plan b pill umm maybe 6 hours later or 7. that night i was running to bathroom so much to pee. i guess that was first effect from it. next day felt like someone punched me in to the stomach .advil  helped. after a week got my period. did couple tests no not pregnant. :) if u use it as soon as possible it will be more effective. good luck!"
