I'm on the Depo shot not for birth control, my doctor thought it would stop my bleeding. I was on it 16 yrs ago, I still had a period. He gave it to me in August and I skipped all of September with no period. Now i started bleeding October 2nd and haven't stopped, it's been 16 days. My doctor died in September so I don't have a new one yet, Does anyone know if this is normal?
