Not sure if I missed my surge?

Lu

So I’m on CD 17 ... glow predicts my ovulation to be in 3 days. I took a opk about 3 pm today and it came up almost positive... so I just took another one (approx 9:30 pm) and it’s now really faint again... I’m thinking this means I may have ovulated today (early) and it’s now fading again? Top one is 3 Pm today and bottom one 9:30pm....

do you think this is likely what’s happened?
