Several high fertility days??

I use Clearblue Advanced OPKs, and I have had high fertility for eleven days now. Still no peak. I am now on CD 24, and my cycles are usually 32-35 days. My last cycle, I got peak on CD 16. The cycle before, peak on CD 14. I am extremely confused as to why I keep getting high fertility, but no peak. Has anyone experienced anything similar? Any help would be much appreciated!
