AMH dropped dramatically in 1 year

Deepshallow87

Has anyone experienced this? I expect AMH to drop with age but mine dropped by more than half in 1 year (from 23 to 10). Is this normal? What are other reasons that can cause it to drop so much if not because of age?

Btw... AMH is a reflection of egg amount/reserve (not quality). High AMH is usually a marker of PCOS (which I do have) so that’s why mine is high to begin with. It’s just the huge drop that scares me.
