Ovulation test help!

Michaela trying for baby number #3

So I took a test on 29th and it came back as peak and then I took a test 30th and it was a blazing positive ovulation test, so if on 29th it said peak but on 30th it didn't say anything. Is it normal to get peak before a proper positive test?? I'm just asking as don't really understand. Test from 30th March!

Test from 29th
