Clear blue OPK users

Tara • Wife. Mom to be to 3.
I've been using the cheap internet ones but I bought the clear blue digitals this month. I used my cheap ones till they got close then started to use the CB ones. Today was my solid smiley face. What do you do? Do you keep testing till there is nothing there? I was reading online and women was testing with a smiley for 2-5 days. What are your opinions on the clear blue?
