I have been off it since May period came back in august just for a couple of days then in september it went of forever, I've never been one for regular periods anyway so working out ovulation dates would have been impossible but at the moment don't even know if I'm ovulating anyway, have read so many stories of people ttc after being on depo and it takes years so guess I am just at the begining of a long wait I wish they'd make it more clear how much it messes with ur body before they give it to you, I only had 3 shots of it so am hoping it may come out my body a little quicker than some but think I'm just getting my hopes up.
