" on may 18th this guy came completely inside of me and he wasn&#039;t wearing a condom/i wasn&#039;t on birth control. around 5 hours later i took plan b. on may 22nd i got my &quot;period&quot; which i later learned was withdrawal bleeding but anyways it was really heavy for a few days and then got progressively lighter. i had spotting for about a week and a half after the heavy days which has never happened to me but i read the pill can make your cycle irregular so i didn&#039;t worry too much about it. around 11 days after the &#039;act&#039; i took a test and it was negative. i waited a week and took another test (so 18 days after the &#039;act&#039;) and it was negative! not pregnant!! yay!!"
