Hope you don't mind me jumping in here.
You might recall that I did the endo biopsy testing in November and with this cycle I used his modifyed progesterone protocal. Certainly I have a long way to go but I'm at least in the running with a strong beta at the first test. I don't even want to count how many fresh and frozen DE transfers I have under my belt but this is the best I have ever achieved. All prior transfers were BFNs or else very low levels of under 20 that petered out.
I've added everything else you could think of in the past: prednisone,doxycycline, lovenox, intralipids (which I still used this cycle too) but this progesterone change just might be the winning ticket for me.
