Your numbers look good. HCG levels are so broard and its not so much about the "number" itself, it's more about the numbers doubling every 48-72 hours. (I think this increases to 96 hours maybe as you near the 8 week mark??)
I thought i sent you a link, but it doesnt appear I have. Here it is again:
Use this, and enter your dates, times and levels, and it will tell you how often your numbers are doubling .
I think you are fine though. . Talk to you soon
