i was on depo for 2 years before i had my son and then i was also on it after my so was born and i gained weight but it wasn't because of eating more. My doc said it was cause since i stopped having my period while on it my
body was holding onto more weight cause my metabolism was slowing down. it was really weird but i have been off of it for a year now and am loving not being on it as i was so moody while on the shot but am going to have to think about another means of bc soon cause my hubby is coming home and i don't want to get pregnant before i get down to my
goal weight. I would say if your main concern is gaining weight workout out and watching what you eat will really help in that department. good luck.
