Hello, I would be happy to help you with your question.
So it sounds like your problems have been present since you started the Depo shot. I will assume that there was not a problem before that point. Given the pain with intercourse and bleeding unrelated to a cycle, you need to be seen by an OB/GYN to have an exam, cultures to rule out infection, and likely an ultrasound
of the uterus
. It might be that the depo shot caused vaginal dryness
or predisposed you to a common vaginal infection
. Go get checked out!
I hope that this helps and good luck!!
