OPK help!!!!!!

Ok ladies, this is my first time to take ovulation tests. this week is supposed to be my ovulation week and tomorrow is supposed to be my high day! I'm so confused! All of my test are negative and on the 9th in the AM it looked like the light was almost to the same color as the test line but it wasn't quite there yet. then all of the other test the line is really faint... I'm so confused on what I am supposed to be looking for. is this normal? could I just not ovulate one month? could my tests be wrong? could the app be wrong? Idk what to do! please someone give me some insite!! Idk what I'm doing!!
