"if you&#039;re reading this, it&#039;s most likely bc you&#039;re freaking out. you took it wanna know if it works or deciding if you should take it, so i&#039;ll share my story. had my period 6/11, had sex 6/28. realized the jerk had taken the condom off during some point of the intercourse once he &quot;pulled out&quot; and his business was all over me. the next day about 22 hours later, i took plan b. felt nothing. no bleeding, no cramps. kinda felt like my period was coming but it never did. 16 days later it finally came! plan b works! also as a tip, stay calm and if necessary try to induce your period."
