LH Surge Question

Tarra
I never post in here. If someone would take the time to look at this and see what they think, I would really appreciate it. 
According to glow, today should be the day I ovulate (6/26). My OPK's arrived on the night of 6/22, so I started them the morning of 6/23. They were rather dark and I discussed it with my husband, and we decided that the tests must just be a little sensitive and they would get even darker when I ovulated in a few days. However, they started to get lighter last night (6/25) and this morning (6/26). Looking at it, I would think I was ovulating when I first started taking the test. And that now the LH surge is dying down. Does anyone agree or disagree? Any thoughts on it? Thanks so much for taking the time to read my post.
