Cancel fresh transfer for progesterone of 1.21?

Tonight is my trigger shot with retrieval on Friday and I just a call from my RE that my progesterone today is 1.21. He said this is on the higher side and they will often cancel a fresh transfer for anything over 1.2 even though research says less than 1.5 is okay. He said its my choice if I want to do the fresh transfer or freeze all the embryos. I was SO excited for the fresh transfer next week. Has this happened to anyone? Any advice or insight is appreciated!!
