First time using an OPK!!

Autumn

This is my first time using an OPK and really our first month TTC. Glow says I should be ovulating tomorrow and OPK says low chance, so I’m confused?? Is it likely I’m not ovulating this month or is it later in the cycle? Also, when is the best time of day to test? A.m. urine or thought out the day? Getting mixed info in my research.
