Bump on cervix growing

So about 3 years ago I got the mirena put it and I notice about a year into having it a small bump appear it never went away and when they checked the implate they said nothing about the bump .. well on the 3rd year it came out and the bump was still there now I noticed it's almost doubled in size And it's solid like I can't move it. But I have no insurance and I'm on a 6 month waiting list for a appointment at a free health center because I have no money to my name I barely can keep food on my table . So I'm hoping this is just a cyst cuz I've had cyst in my ovaries before?
