Ovulation?

This is the first I've tracked my ovulation since my miscarriage last year. My cycles have been 30 days typically. I started testing on cycle day 14. As you can see from the picture, it is the darkest line I've gotten. I've been testing  every day since and the lines are getting more faint. According to glow, I should be ovulating today. Any thoughts on why my tests are so faint?
