Confusing!!!

Ok these were taken the same day! I’ve never used these blue strips, I’ve always used the pink, I apparently ordered the wrong ones, anyways, I’m aware of them both being negative, but their is literally no line on the blue one at all, and I should be ovulating in a day or two. Have any of you taken an opk that didn’t show any kind of line until your peak day???
