can't tell if it's positive

I am currently nursing my little one and have been extra tired the last few days. I took one of these wondofo tests andcant tell if it's positive or if this is just how the tests look. I feel like the faint purple line is there on all the tests and just want to verify that's how this brand works. Thanks!I also notice a line just above the faded line that could be an indent maybe? It was taken within the time frame suggested
