Clear Blue Digital OPKs

Di
I've been using 50 strips for $20 that I bought on Amazon (easy@home I think?) and never received a true positive opk that I was happy with.
 I switched to the Clear Blue Digital hoping the blatant Peak/High/Low would be easier. I have been testing for the past 9 days and received one "low" and 8 "high" but no peak.
Is it possible to ovulate so far into a cycle? Or did I miss it? :( I test with the first urination of the morning.
