WTH glow?

Why is glow telling me I will ovulate in 2 days...my lh surge was Monday then I got it again (wtf) on Wednesday. Negative yesterday and today. So why will I ovulate Sunday? It doesn’t make sense. My cycle is weird this month and my dr can’t explain the multiple positives-having progesterone checked next month at 21 days and ultra sound today post d and c a year ago just to make sure things look good. But I don’t understand their prediction. All my other apps disagree.
