Constant Testing

Hi all, I am officially 4 weeks 3 days pregnant with my first baby and I feel like I am starting to become addicted to taking tests. I found out super early at like 2+5 and I feel like the line on tests just isn't getting any darker even though I have taken a digital. At what point do you just relax and stop testing/googling? I guess the fact it isn't getting lighter is a good thing, and we are going for a private scan at 6+6 but this anxiety and not feeling any different is consuming me!
