"i had to take plan b 2 times and i&#039;m also 168, slightly above the &quot;weight limit&quot;. i should&#039;ve learned the first time but of course, didn&#039;t think it was going to happen again.  i didn&#039;t get any side effects other than swollen boobs the first time and began spotting a week later for 2 days before starting my period. the second time, i immediately got intense stomach cramping after taking it and then fell asleep for 3 hours. i spent the next 9 days stressed &amp; crying, thinking my period wouldn&#039;t come. i had cramping in what felt like my ovaries every night, so i&#039;d think my period was coming, it didn&#039;t. on the 9th day, a full on period. this a very necessary medication but please, don&#039;t put yourself in a situation where you&#039;d have to take it."
