Pregmate False Positive?

I’m not sure what to think of this! I had blood work done Tuesday. Results Wednesday showed negative. Took a test this morning and I think I see the faintest line. So I used same urine and took another test. I did a urine hold and tested again and don’t see anything. I’ve heard potential false positives using Pregmate. What’s everyone else think?!

First set of tests, same urine!

Urine hold!

Inverted from this morning!
