Pos urine tests, neg blood, period 11 days late

Sarah

Hi all - wondering if anyone has had a similar experience? My pregnancy tests have been positive since 7/18, they started getting lighter and then darker again, now lighter. I’ve had blood taken twice and it came back with HCG less than 3. I still feel pregnant, have had no bleeding and am 11 days late. I don’t understand what is going on. Will attach a picture of my test from the morning I had blood taken. Thoughts? Experiences? I’m just ready to move on, but am stuck in limbo. Also, lines aren’t indents, appeared within time frame, have color, and positives on multiple brands of pregnancy tests.
