2 failed PGTA embryo transfers. One last embryo. What were your protocols that worked for you after failed ones ?

Hi everyone, I have had two failed PGTA embryo transfers. The first one didn’t stick at all. It was half medicated, they just gave me a trigger shot for ovulation and started progesterone ovules on day of transfer. Second transfer was fully natural and I started progesterone ovules two days before transfer. I got pregnant the second time but ended up being a chemical pregnancy.

I have one last embryo left which we will be transferring next cycle, which is very soon. I’m expecting my period this weekend.

I have done all tests, hysteroscopy was all clear and good, no clotting issues or protein s deficiency etc.

This cycle I believe the doctor wants to do a natural cycle again but with baby asprin. I have heard that some doctors also prescribe prednisone.

Just wanted to understand other people’s protocols if any one has also experienced this. Because they have not given me an actual reason of why it’s not working. They have just said that I might be on the wrong side of statistics. And I’m scared to use my last embryo, which is also PGTA tested and normal.

I’m 32, and have hashimotos, so I do take thyroid pills every morning, but my thyroid is stable.
