"i took the depo-provera shot starting from 16-20. i absolutely loved the shot other than not ever really knowing when my period was going to be. i actually lost weight on the shot and my breast grew larger than before. i had great sex drive as well. i switched to the levora pill simply for the fact that i knew i wanted to become pregnant one day and knew if i took the shot for too long that it may effect that. i chose levora because i only have 4 periods a year (which is great!). however, i have been taking this pill for 3 1/2 years and i have noticed some negative side effects. i have been slowly over time gaining weight. i also never used to have acne and have some acne problems now. i also have low sex drive and difficulty staying wet."
