"i was on it for about 5 &quot;cycles&quot; which is about 15 months. after the first month i did not get my period anymore or spotting. i have been off of it for almost a year and still haven&#039;t gotten my period. for me it was quick easy convenient, i had no side effects what so ever...except the weight gain. i started right after i had my daughter and i was about 215. i am now pushing 270 (don&#039;t judge). i fully understand the shot itself cannot make you gain weight, it just gives you more of an appetite but my god, that&#039;s a lot of weight in a year and a half. i am also convinced it messed with my metabolism but there&#039;s no medical evidence i can find to support that. it&#039;s also scary how strong of a dose of hormones it is."
