Ovulation tests

Does anyone experience different results with different ovulation tests?

I have pcos and I could ovulate between cd 16-24 so I have been using one step ovulation tests as a cheap option. I decided to try the clearblue digital but they’ve been negative. I used easy@home one month which resulted in a chemical pregnancy so I decided to try them aswell this month. The easy@home looks the way it has in the past the day before my peak, yet the other two tests are still negative.
