Due date 10/8 hcg levels

Hi y'all! I found out at 10dpo I'm due with my second child! This is my 3rd pregnancy, my first was a mmc, second my son is 2 years old now, and now this pregnancy. I had progesterone and HCG work up, progesterone was 9.8 so I'm on suppositories now. Hcg went from 27.4 on 11dpo to 75.4 only 43 hours later. The nurse said that everything looks great! I am just still taking multiple tests a day because I'm so scared to miscarry again. Do y'all think that the odds are in my favor, and I should just relax now?
