"i switched from orsynthia to kariva due to painful sex. i was cautious to try it seeing all the bad reviews but i&#039;m glad i read them considering i had many of the same problems. first of all, your period should come during the first two days of the placebo week, that didn&#039;t happen. i got my period at the very end of the week each time with bad cramps. flow wasn&#039;t terrible still kind of heavy for birth control though. i also didn&#039;t like was how many headaches i would get; at least 3-4 a week. i would also feel very foggy and tired all the time. my appetite has definitely changed on this also, i would constantly want to eat all the junk food i could find. didn&#039;t gain much weight but still. boobs also got bigger. i&#039;m changing back to orsynthia!"
