Slow and steady....what do you think??

Nicole • ✨TTC #1 since 10/1/18✨👼🏻

So my app says I ovulate in 4 days but my strips are slowing getting a little darker each day but definitely haven’t hit my surge yet with that being said does it look like the app could be a little off then since I haven’t gotten a surge yet don’t they said after that dark positive it’s 24-36 until ovulation or do you think I’m on track to still maybe ovulating in 4 days?
