"i never got my period regularly, but i once i started taking this i stopped getting it altogether. no joke, i gained over 50 pound in the year and change i was on this, and i can&#039;t attribute more than maybe 5 or 10 pounds to lifestyle changes. i went from an a/b cup to a d cup as well, and towards to end i was exhausted 24/7 and sleeping up to 18 hours a day. i can&#039;t say much about what changes once you stop as i&#039;ve only been off of it for a week or so now. i take other medications too, and this was the first birth control pill i&#039;d been on, so i wasn&#039;t sure at first if the birth control was the one causing all this for a bit, but i&#039;m fairly certain it is now."
