3rd miscarriage and progesterone

I just suffered my 3rd miscarriage. Heartbreaking. I was on progesterone this time around and I don’t think it did anything but let me hold on to a non viable pregnancy. Found out at 9+6 our baby has stopped growing at 6+1. 2 days after I stopped progesterone I’ve started spotting without having to take meds or d&c. Next time I don’t think I’ll be able to bring myself to take progesterone as I feel like it’s gave me false hope. Anyone else have any similar experiences here?
