What does a typical FET cycle at your clinic look like ?

I am prepping for my second FET next cycle. My last FET was in March (Euploid 3AA and it failed to implant). Here’s what the FET calendar looked like (this was a modified natural) -

1. Called the clinic on CD1

2. Started birth control pills from CD1 to CD9

3. Waited for the period and started letrozole cycle day 3 to 7.

4. Baseline and follow up ultrasounds

5. Trigger (after a low dose of Gonal F) + started progesterone suppositories 2 days before FET

6. FET day: 5 days after ovulation

Is that how a modified natural FET cycle looks like in your clinic as well? The birth control pills add an extra 10ish days which makes it kinda long , I am wondering if it’s common practice ?

Second question - has anymore tried modified natural + PIO shots ? Instead of the prometrium ? PIO shots do give the body more systemic progesterone , but not sure how common this hybrid approach is?

Appreciate any insight into this!
