"i started the shot when i was 17 after a miscarriage, my period has always been irregular but once i started the shot i bled for a month straight. after that first month i stopped having periods all together. before i got on the shot my weight was consistent always stayed around 120.. but after my weight started going up, by the time i was 18 i was going on 140. during my second semester in college i got off the shot because i didn&#039;t like the fact that i was gaining so much weight, before school started back i got back on the shot bc it was much easier than taking the pills, and my period was a mess i never knew when it was coming so i wanted to put a stop to that. now i&#039;m 19 and pushing 170 i have gotten off the shot and refuse to take it"
