High progesterone causing implantation failure

With both of my daughters I did 1mL twice a day of progesterone.

My clinic checks progesterone levels at 2dp5dt

Daughter #1 was 40.30

Daughter #2 was 55

We have now done 2 FET cycles and both failed but my progesterone was extremely high due to them upping my progesterone to 1.5mL twice a day. My levels were 94 and 141 my nurse said it’s fine as long as it’s above 40 but that seems extremely high and when I research it says it can cause implantation failure has anyone else had this happen and lowering progesterone amount helped?
