Beta only 6 with positive HPTs

So I’m looking for some positive stories (or stories similar to my situation). I had a positive first response a couple days ago, and went in yesterday for my beta. It came back at only 6 (I was 11-12 dpo). I took a test right after the blood draw and it looked like this:

I’m so shocked it was this positive! My nurse seems to think it might not be a viable pregnancy, but I’m having a repeat blood draw again tomorrow to see if the HCG doubles.

Here are today’s tests (12-13 dpo):

Has anyone had a beta this low at 11-12 dpo and still had positive hpt?! And had a good outcome?

Thank you!
