Euploid FET failure

I’m 39, and looking at IVF round 5 for baby #2. I have DOR, so I’ve only ever gotten 2 blasts to PGT test at most, and some rounds nothing. Only 2 of 4 ever tested were normal- one is my precious daughter, the other just failed. Anyone have anything similar happen and willing to share their protocol so I can ask my doctor about it? I have added omnitrope, which has gotten us our only 2 normal embryos (I believe!). Thanks all ❤️
