"i was on yasmin for about 5 years had no serious problems with it and it worked great as a form of birth control. i gained weight but not sure if the pill is to blame. i had irritable mood swings but nothing too bad. the one biggest side effect for me that made me switch was the migraines i was getting while taking the placebos. each and every month i would have migraines while on my period. but other than that i love this pill, my periods were always on time i had short 3-4 day periods with minimal cramping. i have just started taking levora, which my doctor recommended taking 3 straight months and then having my period to minimize the migraines. so far i&#039;ve had breakthrough bleeding and heavy as well for about a week. i hope it gets better."
