Conflicting test stick and monitor information & no peak!

Hi, I just started using the clearblue fertility monitor and immediately from the first test (Tuesday) saw a high fertility rating. It's now Sunday (6days of using/day 10 of cycle) and I'm really confused about the results so far. Visually looking at the sticks, I saw the two lines progress to what looked like it was about to peak (2 strong lines exactly the same) to a single line today, which indicates a low. However the monitor still says high. What should I do? Should I stop testing and assume i missed my peak, or will it confuse the monitor? If I carry on testing, am I unlikely to reach a peak, given the results shown already, am I just wasting my time and wasting the sticks I have left? Please advise. I have pics of the tested sticks I can send if you want to see them.
