Pregnant after 2 losses & progesterone

I found out today at 10dpo I’m pregnant! I’m so scared worried and desperately praying I carry this baby healthy and safely for 9 month long. Dr has put me on progesterone straight away. Does anyone have success with this? Also How do you get over this fear of loss again?
