"i started using depo when i was 18 after the birth of my first child. worked excellent!! 0 complaints, i had no period,weight gain or emotional crap. i loved it plus i was breastfeeding and it didnt mess with that. i used it for 3 years. i quit and about 6 months later got pregnant with my second baby. about a year and a half after baby #2 i tried depo agian.... i was moody but not to bad and agian no period.. took it at the 3 month mark and it bit me in the butt badly... i had every bad side effect possiable. i felt like i was crazy and pregnant, had constant spotting it was horriable. needless to say i stopped.. and about 6 months later was pregnant with baby#3  my doc tells me its a great bc for younger girls....."
