Positive urine tests, negative blood?

Has anyone ever had this happen?? I’ve taken seriously about 20 home pregnancy tests (don’t judge me lol) over the last 3 days and all have showed positive. I’ve even tracked line progression. Went for early bloods yesterday and it came back as negative, hcg only 4? I retested a home test this morning and can still see line progression from yesterday. I read that bloods pick up lower hcg and are more accurate, but what is going on??

Edited to add: I don’t believe they are indents, as they have color.
