Depro Vera Shot

I was on the Depo shot for about 2 years before I decided to stop so that I could get pregnant just once more. It has been 2 years since, and I am constantly bleeding. The doctors nor the nurses that gave me the shot never told me what the side effects were until after I decided to get off of it. I am worried that I will never be able to have another baby and it hurts to now that I made a big mistake all because I thought it was a sweet deal regarding not having your period while on it. I hope that I will be able to meet up with a doctor that can help with this situation because it feels like who ever I turn to in order to help fix my cycle basically has no answers.
