What was your HCG in early pregnancy?

So I just found out I was pregnant last week and last Tuesday my bHCG was 24.9, last Thursday was 64.9, and today it was 113. I'm currently 4 weeks and 5 days pregnant but I'm worried that even though my numbers are going up they're not going up that fast for one and secondly my progesterone went down a little bit. They said both were good but does anyone have any stories they can share with me on this subject? I'm hoping I don't lose it because the numbers didn't "double" like it says they should every 48-72 hours this past blood draw.
