"was prescribed this form of birth control for the horrendous period cramps i&#039;ve struggled with since first starting my periods back when i was 11, always has been a major issue, no solutions were able to be found regardless of all the &#039;natural&#039; means i had tried. very effective in eliminating cramps and lessening the flow, am not left only to lay in bed in agony, often forget that i&#039;m having my period now. no real side effects besides muscle cramps at times and very sore breasts off &amp; on, along with mood swings, but it has been very worth it, wish i had gotten on these pills sooner, quality of life is much better. highly recommend trying them, it has been life changing."
