RAN OUT OF OVULATION STICKS AT HIGH FERTILITY!!

I have been using clear blue advanced digital ovulation kit for a week now and i was at 7 days high fertility (and took 2 in one day on 3 occasaions) I ran out of sticks at high fertility (flashing smiley face) and never reached the peak fertility face!!! Do I have to buy ANOTHER KIT?! I'd rather not at $50 a piece! Ughhhhhhh any suggestions? Or should I just keep having intercourse each day and hope for the best?
