Hi i am a 29 year old female. I got my first depo shot in april 2012 and it worked pretty good. two weeks before i was due for my next depo shot i started bleeding , i figured it was due to the shot wearing off. However, I have been bleeding for 3 months everyday! my doctor put me back on necon birth control and i have been taking it for almost a month now and I am still bleeding, not as heavy as before though but still bleeding. What can be done? When will the bleeding stop?
