Vvfl or bfn?

At 8DPO I took a pink dye test and a very faint line showed up, at 9DPO I took a blue dye test and it also came back as a faint positive. This morning I took my second blue dye test and it came back also with a faint positive, but it was a little darker. Later today I decided to get another pink dye test but I have no idea if I’m just seeing things or if there is a vvfl. Any thoughts?
