What is going on with my body?!

Hey Ladies! I need some help. I've been testing my ovulation since I got off my period because I've been so anxious. We're TTC our first. I've been testing everyday for about 9 days and it has been saying low fertility and I know my "fertility window" starts tomorrow according to glow. I tested this morning (9:00am) and had low fertility and just randomly decided at 11:21pm to just test and I got my peak of ovulation... Is this even possible to totally skip "high fertility"? I'm just so confused!
