when do I stop testing 🙈

Kay
I started at 3w5d and I'm 5w tomorrow...I don't have a scan until the 6th...I've been taking these to make myself feel better...but when is it time to cut the cord?
Last pregnancy I tested until all of a sudden the test got mysteriously light/almost BFN over night Bc my HCG had gotten so high the test couldn't read it properly (hook effect). And I have a healthy son now.
But that was so stressful and scary...
I just have no symptoms and no reassurances that my pregnancy is going well. The lines look like they are progressing? Maybe it's time?
