If this is your first month, it may take a while before you see the peak.
Your monitor will need to "get to know you" this month.
I am also in my first month of using a monitor. I started testing on CD 6, had 4 days of low, and 10 days of high, I finally got my peak yesterday at CD20 and another peak today at CD21. Now obviously I am a late 'O'ing person, so if you 'O' more around CD14, you won't see as many high days this first time around as I did.
But I agree with the above post, BD now

at least up until after you reach your peak.
If you don't fall pregnant this month, next month the monitor will probably give you less high days since it had a cycle to 'figure you out'.
Good luck!
