Clear Blue Digital (advice please)

Jazmine • Fiancée and I are TTC #1. Excited and blessed.
Ok so my partner has been takin clear blue digital ovulation tests for the past 6 days. The last five days we have gotten "high results" but no "peak" day. She has an average 35 day cycle. I'm just wondering it this is normal for anyone with a long cycle? Will she ever get a peak day?
Thanks 
Jazmine and Shasta
