Hcg levels

Megan
What do any of you know about hcg levels? This is my 2nd pregnancy--the first one ended in a mc at 9 weeks. When I got blood work done the 1st time the hcg was 888 at 4w6d and now when I got bloodwork done at the same time frame with this pregnancy my levels were 5349! I am currently 6w5d and nervous I just want a healthy baby.
