Cycle confusion

My cycles are usually on point, 28-29 days. I've had ovulation cramps last night and most of today. But when I look at Glow, it shows my period won't come until CD 35. But when I do the calculation for my normal and regular cycle, I should be starting on the 24th (next week). Does that mean I'm ovulating too late or what's going on? And will this affect my chances to conceive?
