Was this LH surge?

Katie

I tested multiple days and this was the darkest out of all my days before it got super faint again, but the test line doesn’t look as dark as the control? I have 3 different apps, all are giving me different period dates ranging between tomorrow and Sunday. I’ve taken some preg tests and all are negative. I’m wondering if I messed up the assumed ovulation time based on this LH Test (was on 7/10)
