I occasionally bleed during sex. I'm on the Depo-Provera shot. Could that be the cause of it? It started last year and I've become a little more conserned since it hasn't stopped yet

See your doctor. There are some women who will experience spotting while on depo-provera shot. However, this is not common. If you are bleeding only during sex, there may be another reason for this. See your gynecologist soon.
