Femara after Clomid

Doreen
So I did 5 rounds of Clomid, spaced out over 2 years and now have thinning of the lining of my uterus. This can lead to miscarriage if I conceive. So now I do medicine rest (no fertility drugs) for 2-3 months then try Femara. Anyone have success with Femara after Clomid??
