Ok so I was on depo about maybe 2 years ago for my first time and when I went to get the shot I was already on my period and after a couple days getting the shot I stopped bleeding. And I probably got 4 shots after the first one before I stopped but I never bleed. Now I just recently got back on depo and I've been bleeding for like 6 days straight now. Will it go back to how it use to when I first got the shot? Or can I stop the bleeding. Thanks
