BFP or BFN?

I couldn't sleep last night, and even though I promised myself I'd wait three more days, I went ahead and took a test at 4am and this is what I got... I took another one at 6am and got negative. I've heard of evaporation lines.. is that what this could be? Or is it just that I may have used my "first morning pee" on the one at 4am. I'm headed to the store after work to get more tests!!! Praying this is our BFP!! 🤞🏼🤞🏼
