"i have been using birth control for going on 4 years, 16-20. i got on them for the purpose of i have extremely heavy periods with horrible cramps and acne. i took levora for about 2 years (no sexual activity) and i took it non stop to completely stop my period. bad idea. i had break through bleeding and severe cramps for over 3 months of heavy bleeding. they put me on the strongest pill possible after that to try to stop my period from the continuous bleeding, didn&#039;t work although i did loose a lot of weight.. for the last year 1/2 i&#039;ve been sexually active and the strongest pill didnt work so they put me back on levora with a seasonal period, and i haven&#039;t gotten pregnant and my acne is good and my period is gone! other than every season."
