Confused??

I took an ovulation kit today out of curiosity because I was cramping, & it came back positive. According to Glow, I've already passed my fertile window. I'm on CD22 & my CM isn't what it should be for me to be O. It's EW instead of watery. Can someone please clear this confusion for me? In my past experience at my OB-GYN, I had a vaginal ultrasound done & I was about to lose my egg on CD20. Is this mix up of everything the reason why I've been TTC for 10 months? I don't understand what's going on with my body.
