"please don&#039;t judge this post..i&#039;m here to share my experience with plan b and provide some hope for others in the same situation i was in. i stupidly had unprotected sex more than once in a several week time span. i took plan b twice within a few weeks of each other. up until then i had pretty normal periods and no major issues..after the second time i took it i had insane cramps, back aches, sore breasts, you name it.. i was convinced i was pregnant but all tests were negative. i just got my period..exactly 8 weeks after my last one. so taking plan b, especially more than once, really messes up your cycle and the added stress of thinking you may be pregnant doesn&#039;t help either. i&#039;m also well over the &quot;weight limit&quot; and it still worked."
