Yeah, I definitely see your lines! I didn't see anything at all on mine and I even took it apart and nada. I figure 10dpo is still kinda early, and I don't think I had been holding for that long yesterday anyway, in addition to it being an evening pee lol.
Oh, and I was also reading that the fs tests don't tend to work well for early testing, that they are more accurate for testing AFTER your period is already late, but I don't know how true that is.
