Pregnancy Test & HCG Anxiety

I have been a wreck since I found out I’m pregnant a little over a week ago. It’s a much wanted pregnancy but I’m afraid I’m heading for a chemical. I am 5 weeks 3 days today. Last Monday my HCG was only 16 and last Thursday it was only 20. I got another HCG blood draw today and results will come tomorrow but the wait is killing me. I took a first response pregnancy test (early detection) yesterday and it was darker than the last so I finally started to feel relief. This is the top one pictured. All the ones before it were incredibly faint. Today I took the test pictured on the bottom. I am a wreck. The only “optimistic” thought I have is that since it was a different kind of test - first response rapid test (1 min result) - that maybe it has a harder time reading HCG? But even then that tells me it’s still low. I am just having a really hard time holding it together
