OPKs clearblue - no high, only peak

Hi All
​Been using clearblue OPKs and I never get a flashing smile for "high". I jump from low to "Peak" smile. Anyone else seen this?
​Since I don't get a lead upto the peak ovulation day, have I missed my chance ? 
​Also clearblue won't let me retest the next day after a peak.  Any ideas ?
 
​Thanks & baby dust to all x
