Possible Rainbow Baby?

I had a missed miscarriage in July at 10.5 weeks. At the end of August my levels finally reached zero and I got multiple negative HPTs. Starting feeling some pregnancy symptoms and took a test on Saturday the 23rd and I got a vvvfl (top test). But then I tested again this morning and got a negative (bottom test). I'm assuming it's a chemical pregnancy, but some people are telling me there's a second line on the bottom test. I can't see it at all, so I'm just looking for honest opinions. Negative or positive?
