New RE consult today.

I consulted with a new RE today.  His clinic is about an hour away, but has very high success rates.  It was a very interesting meeting and much different from my current clinic.  I loved it!  It's a smaller but very patient-focused.  I met a lot of the staff and sat down with all of them.  The doc reviewed my records and has a very interesting theory of why my IVF's failed.  He looked at my P4 (progesterone) levels before the transfer and found them to be way too high.  (At the first IVF, it was 2.8, the FET it was 1.8).  He says that my uterus was no longer receptive to implantation with those progesterone levels.  Basically, the uterus was not in sync with the rest of the body.  I've been unable to verify this via Dr. Google, but an interesting theory nonetheless.  He suggests a hysteroscopy, then an FET taking steroids throughout the cycle.  I'm consulting with one more clinic next week but will probably go with him.
