LH questions

So this is my fertile week according to Glow. I have been testing once a day up until my fertile week then went to 3 times a day (we start seeing a fertility specialist if this month we don’t conceive, blood work scheduled for day 3 of my cycle) so I really just hope we make it happen this month. These strips are driving me bonkers. Did I have a surge? I would say no based on it needs to be as dark as the control line and none of them are. But also my CM was on point for being fertile and the lines today are getting even more faint. Is that a surge on the 27th? Thoughts?
