Accidentally tested twice on low (O)

I accidentally tested twice in one day on a low ovulation day (O) it was low both times, but then the next day I got a blinking :-) but it hasn’t stopped blinking since then. Should I have retested on a new device? I know it says you can test twice a day once you get High fertility, but I accidentally did it during the low period and never received a peak just keeps blinking.
