"i wanted to share my opinion of loestrin after reading the other reviews because i found it so interesting how birth control can so differently affect different people. i switched to loestrin from yaz about a year ago and have been much happier. i was put on yaz to control my mood swings during my period but it ended up making me experience periods that would last 2 weeks with very heavy bleeding the whole time. i now have very regular, light periods with loestrin and it still controls my mood swings. i do notice more breakouts but nothing ridicuouls just one or two more pimples rather than none. no weight gain, no headaches, no other problems."
