Progesterone 175 nmol/L day of Fresh Embryo Transfer

I have a double embryo transfer of a 3BC and 3CC yesterday. They took bloods at the time and this morning the result was 175 nmol/L which I found to be very high. Before leaving the clinic I asked my consultant what level would be ideal and he responded over 30 but less than 100. However, this morning he said I have an excellent result but he would like me to reduce my progesterone medication. I’ve read online about high levels at this stage causing asynchrony between the endometrium and the embryo impacting implantation. Has anyone had any success in this situation with fresh transfers? I think frozen is slightly different. It’s our last two embryos and now I’m scared it didn’t work for this reason.

I wanted to add this happened on a previously cycle which failed and they put me on the same amount of progesterone again. 3x cyclogest pesssries and lubion injection alternating days. I’ve now been told to take the lubion every 72 hours instead of 48.

I haven't had your experience, but my understanding was you couldn't really have too much progesterone (not a Dr though!) Sending you lots of luck xx

@Orangewillow Thank you for your response. I just feel rather let down by my clinic again.
