HELP! ovulation test

Today I decided to take 2 different tests each time (the other bigger test for 1pm isn't here but looked like the bottom one which was taken at 7:15 with the bottom smaller one) I wanted to see if how close they were and how the results on the 2 different brands would compare but now I'm very confused because the smaller ones both seem to be positive I think but the bigger one isn't..I have had EWCM for the past week today has been the most though would you say this is positive or negative?
