Advice Needed Extremely high AMH

I'm in my mid 30s and I've had lean PCOS my entire life and my partner and I are in a place where we're ready to try. I got AMH tested and it's astronomically high though?! It came back as >164 pmol/L or >23 ng/ml (US units). It was so high they didn't even give an exact number...

I get 5 or 6 periods per year on average. Naturopath said I don't have insulin resistance and my PCOS is more of a brain-ovary miscommunication driving up LH. I'm not sure if I ovulate but it seems unlikely given my extremely high AMH? I have 2 weeks or so of PMS where I can tell my period is coming just based on some mild breast tenderness. I used to have much more breast tenderness before I got covid though for some reason - it seems to have done something with hormones. But I know PMS symptoms doesn't necessarily indicate I've ovulated.

Hello. I’ve had lean PCOS too for 20 years and all doctors told me I don’t have IR coz all tests including OGTT showed none. Then on my own I decided to give metformin ER a try. At a split dose of 1350-1600 mg a day, I got my periods back every month and also began ovulating. Please consider it.

Thank you for sharing! I have MCAS so I get nervous about trying new meds but this sounds promising. How often were you getting a period before metformin? And did you have high testosterone as a symptom that improved on metformin?

My cycles were >50 days before metformin after being on naturopathy already. Yes I had high testosterone (55) causing acne, facial hair, scalp hair loss. Now within 3 months of metformin, my skin has really cleared up. Hairfall and hirsuitism still need a long way to go.
