HCG stimulation/Infusion for FET

MakingBabyA

Hello, just checking to see if anyone did HCG stimulation for a Frozen Embryo Transfer. It basically means a small unit of HCG will be infused into your uterus a day before transfer. This is different from the HCG trigger. I got this done and I’m kinda confused on when to test at home. I did not test out the trigger. Doctor mentioned it was just a small unit probably 500unit or so. This is a new protocol to me and I want to know if you have heard or gone through this before.

Thanks.
