The injection caused a lot of bloating around my stomach and my breasts got smaller,did anyone have a similar experience? How long did it take for the body to get back to normal?

I've been on a injection similer to Depo for 2+ years,my last shot was 5 months ago and my doc said that by 5-6 months it should be out of my system. Untill now i have not seen any changes,i heard Black Cohosh could help speed things up,is that true?
