Pregnant with hypothyreose

Hi,

So Im currently 5 weeks pregnant, and super exicted. Unfortunatley my anxiety takes over and Im worrying alot about miscarriage. Im 24 years old and this is my first time. I read everywhere how common misscarriage is. I also have hypothyreose, and I know that can lead to miscarriage. I get treatment for it, and im stable with no symptomps. Anyone out the who can calm me down? Any experience with hypothyreose and pregnancy that went just fine?
