Clearblue Advanced Digital went directly from Low to Peak

Pri

Hi Ladies! I have a regular 28 days cycle and I started testing on CD 10 with Clearblue Advanced Digital ovulation test (the one with three circles- Low, High and Peak). I got Low fertility on CD 10 and 11. On CD 12 it straightaway shooted to Peak fertility (solid smiley). I did not get any High fertility days. Is this correct and normal? Should I BD the next three days. In the past cycle, I got my Peak on CD 14. Any advise will be helpful!
