How common are indents on Wondfo strips? I could've sworn a shadow popped up within the 5 min window, but I also know line eyes are very real. I took a photo and tweaked it out of curiosity (and probably a little desperation, let's be honest - I know tweaking isn't recommended). Only 10dpo, FMU, and with far too much time on my hands today. (I also know the only answer is to wait and test again, which I will do, but I do love looking at other people's faint tests and learning)
