Anxiety???

Is anybody else being super worried this pregnancy? This is my second baby and with my son I was just full of excitement and I don’t remember being so anxious and worried about every little thing. I had my hcg drawn on Monday at 4 weeks and 6 days and it was 449. I had it drawn again today and I will hopefully hear back tomorrow before the weekend to know if they went up as they should for a 2.5 day period. I have also been testing every day (bad I know) just to try and keep my mind at ease. The past three days my tests have looked like this, should I just stop testing? I don’t know how to keep myself from thinking something “bad” is going to happen
