I'm 44 And Had An Endometrial Ablation At 39, So

I'm 44 and had an endometrial ablation at 39, so I haven't had a period in 5 years. About a year ago, I started having hot flashes. They have gotten better, but I mentioned them to my doctor in August and he had an FSH test done. It came back that my FSH was 95, post menopausal. I don't understand how I can be 44 and my FSH level be that high. I've read that 95 would be high for a 60 year old.
