Clearblue Digital OPK's

Ay
I've been testing since Cycle day 9 and I've got PCOS.Got a negative on my first day and have been getting high fertility since then ( I'm on cycle day 17 now). 
Will I have a peak day or will it just not happen. Also which OPK's are better for women with PCOS - the Clearblue normal or the advanced ones?
