Primary ovarian failure

I've just come off Nuva Ring, been diagnosed with primary ovarian failure and started HRT. My doc said my endometriosis would no longer be an issue and she didn't think I'd likely get many periods and certainly not regularly. She actually tested me for celiac (neg) when I said I'd been having a little bit of pain that I thought was from endo and being off BC. She said it couldn't be the endo. I just saw her 3 days ago. But now the pain is worse (although not horrible - yet) and I swear I'm ovulating (based on pain and mucus). I'm so confused. I guess I just have to wait 2 weeks and see if I get a period (in which case she said to call her)?
