"i started the shot when i was 14 to regulate my periods and as i&#039;ve read a lot of women say it made them worse, but for me the first few months made it worse for me i bleed for almost 2 months but after i got my second shot my periods stopped completely. it is also a great birth control, personally i gained only alittle weight (5-7 pounds) but i liked it because i&#039;m considered smaller than average. my stomach gets bloated and my back hurts when i&#039;m due for my next shot and i get a little moody but other than that it&#039;s been pretty good. my breasts and bum grew which is a plus. i recommend it for a birth control."
