Clear blue digital ovulation test

I have been trying the clear blue advanced ovulation tests but I started taking them on the 24th and got two negatives, so 24th and 25th, then one high on the 26th and a peak the following day. I bought the regular to check if I would get the same results and I got a negative the afternoon of my peak...I’m not sure if the advanced are more accurate and able to pick up smaller amounts and/or I just missed it with the other test...anyone else only ever get one high fertility day with those tests?
