Clearblue said peak fertility on first day using it?

Hi! I just started using Clearblue ovulation test for this cycle and on the first pee it says peak fertility...not even a flashing smiley showing high fertility but a normal one. It's only day 6 of my cycle, my period only ended a couple days ago.

Other times I've monitored my ovulation with this and other tests it doesn't come until much later like day 12 to 16.

-Test is new and not expired

-Peed on it right after my longest sleep as they suggest

-Not on any hormones, drugs, or meds

-I am not as familiar yet with the other modes of monitoring ovulation like cervix position etc yet so can't use for cross comparison....gotta get on it in future tho it seems!

Thanks!!

Any ideas??
