Ladies I need some advice please?

Glow predicts I should ovulate in next two days, so I would have expected my lines to be getting darker?? Could a positive result appear suddenly??

My cycle tends to be around 34 days and today is day 20, been keeping a close eye since day 13 with the cheaper sticks and then started using CB digital as well once a day since fertile window.

My digital results have all been empty circle so far. Bottom stick is today and have been doing them once a day so far.

Sorry no dates on them but grouped them into days with most recent (yesterday) at bottom 🙈
