Can progesterone be too high for FET?

Hi all

I am having my frozen transfer in 2 days. I had a blood test today to check my progesterone, it is 140nmol/l. They wanted it to be higher than 60.

Looking at some studies online, a couple recommend an ideal window of 60-100 after which success is lower, so my level is already high and still two days to go before transfer! Clinic have not advised my to change my dose (on 2x 400g pessaries and alternate days of PIO injections - seems a lot!). They seem to think anything over 60 is fine. Don't know if I'm just stressing too much, but anyone else had high progesterone?
