"i have been on this birth control for 7 years and do not have complaints. i never experienced negative side effects and did not gain any weight. before going on this birth control my periods were irregular and had been for 6 years. i can pretty much predict the hour i will get my period each month. my periods only last 2-4 days now and are very light. the only &quot;problem&quot; i have had is over the past few years i have skipped a few periods (about 3 or 4 a year). i talked to my obgyn and he said that is nothing to worry about. overall, i think it&#039;s a great birth control."
