TTC & Ovulation

Would any of you lovelies know-my first time working with Ovulation tests this month and will be coming on fertile time next week. I noticed already (2days only post period ending a little cramp this AM) Let's say I ovulate but miss getting a positive test...will the test I take after show a negative? I know that window of getting positive for ovulation is a tight window so was curious...it would just be negative right? Any help/advice, so grateful appreciated. And what a great forum for us gals!! Yay for all of us!! Baby dust to ALL!!
