How to get over fear of losing baby

I’m 4w2d pregnant so I am very early. I’m 22 & I’ve never been pregnant before, but my husband and I tried for a year to get pregnant before finally getting our positive last Friday. I’m so scared something will happen to this baby. I did get bloodwork and my HCG & progesterone levels were great, and I went back today to get more done to make sure my levels are increasing as they should (i’ll get the results in the morning). I feel like I’m walking on eggshells. I’m scared to move or do something wrong to lose this baby. I cut out caffeine and everything else that shouldn’t be eating or drinking and started taking prenatals the day I found out and just trying my very hardest to be healthy for this baby. How do you get over this fear?? I’m so scared that I can’t even be really excited.
