Clear blue advanced ovulation tests 💜

So today was my first time using the clear blue advanced digital ovulation test and I got a peak result (static smiley). I’ve read that you’re meant to receive a low result so the test can see your base level and then get a high and/or then peak result. I’ve  also never got a positive test this early in my cycle. Has anyone else got a peak the first time they used it? Should I assume ovulation will occur in the next 12-36 hours? Or is my test stick broken?
