3 days of positive opks?

Jamie • 👨‍👩‍👦🤱🤰#2💍💙💚

Is this possible? They've been the same color for 3 days? I've read it's rare but I dont know if that's what's happening or what?

Update: 1/9/2020

It has finally dropped, this other app saying my peak day was the 7th. So would I be 1 dpo or how does this work?
