Prenatal Anxiety

I would like to know other peoples experience with HCG quantitative levels. I had my first draw when I was 4 weeks 3 days on 12/29 it was 93.3. I went back in at 5 weeks on 1/2 and it increased to 399. Are these two low of levels? The nurse said it should of been around 265 by calculation. I’m think those are low hcg levels.. I have read some women with some in the 1000s already at my point of pregnancy…Just wanted to ease my mind. Just anxious until I get that first ultrasound. Will any of you share your experience with me please?!
