Mirena adjustment

Th

I got my Mirena put in about 8 months ago. I have been cramping almost constantly and spotting about the same. I’ve massaged my gyno more than a few time about it and she keeps telling me it’s normal but to tell her if it gets worse. What does that mean? I thought these cramps were supposed to go away. Isn’t the adjustment period only supposed to be a few months? I don’t know if it’s relevant, but she suspects I may have mild endometriosis. And I do have high risk hpv. I’m so over being in pain all the time. What do I do besides wait?
