Anyone know the chances of miscarrying 3 times within a year?

I start TTC baby #4 May 2019. I had a miscarriage at 5+6 June 2019. Then another miscarriage at 7+2 in end of Oct/Nov 2019. I’m worried I’m going to miscarry again. Does anyone know of the chances? I tried to google it and just got confused. TIA 🤞🏻❤️

Edit- last pregnancy I was on progesterone and I do have a -rh blood type.
