Hi all! First month of using premom and second month of TTC. All advice welcomed!

I took opks throughout the day because my surge was so quick last month I almost missed my peak.

My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> is saying I ovulated yesterday, but premom says it’s today. How soon after the LH peak is ovulation? If we can’t do it today due to our work schedules, is tomorrow morning too late?
