New protocol after failed FET

After practically begging my RE to let me do a kitchen sink/antihistamine protocol they finally agreed to let me do this:

“For programmed FET, patient to start Prednisone 5 mg daily, Claritin 10 mg po daily, and Pepcid 40 mg daily day prior to FET. Pt will continue until 8 weeks EGA. Pt should then take Prednisone 2.5 mg daily for five days and then stop.”

I am also doing 10units Lupron once daily that I started with my last 5 days of birth control and continue to do so until I’m told otherwise

My questions for you wonderful people:

1) does the prednisone dose seem low?

2) is starting the day before the transfer even enough time for the meds to do anything?

3) I started to take 81mg baby asa daily even though the protocol doesn’t mention it, anyone else do this?

This is my last solid grade euploid embryo so I really wanted to do everything that wouldn’t cause harm and I know some docs don’t believe that the antihistamine protocol does anything but hey, I’m willing to try anything at this point.
