is that a good progression?

I can't help but worry myself sick since I had a missed abortion last time. One of the early symptoms of the miscarriage was the fact that the HCG didn't go up as quickly as expected. So now I keep taking pregnancy tests to see if there's still a line and how strong it is.
What do you girls think? Is this good a line progression or should it be stronger by now?
