False positive?

Heaven

First photo taken within time frame is from yesterday at around 8pm, I had been holding it as I was napping before I had taken it, test had even gotten darker a couple minutes after photo.

The second picture is from this morning with fmu.

This is my first positive after a horrible miscarriage last year and I’m feeling really heartbroken right now. How common is it that these give out false positive, could it more likely be a false negative?
