Please help !! Ovulation stick

Swathy

Since 3 days I have been getting only high fertility ( flashing smiley ) when I am checking the ovulation using clearblue digital ovulation stick. I usually get flashing smiley only for a day and the next consecutive day will be solid smiley which is peak fertility.

Please let me know getting only flashing smiley for 3 consecutive days is something usual or unusual.
