So confusing...

My ovulation day (according to the app) is suppose to be Friday. I took two different brands of ovulation tests and the app said several times it was positive. I re-did it about 3 times each. Looking at it myself looks like a negative..what do you guys think? Not sure why it would say positive. I saved it as negative and the app changed my ovulation day to tomorrow🤷🏼‍♀️🤔
