CB Digital Ovulation Test Uncertainty

Hi! So I have the tests that predict your 4 most fertile days & I have gotten 4 flashing Smiley's in a row.

My friend gave me the rest of her tests and they are the ones that predict your 2 most fertile days. Anyways I cross checked them against each other yesterday & today.

Yesterday: 1 flashing & 1 negative

Today: 1 flashing & 1 solid smiley

Should I trust the 4th flashing or the 1st Solid from the other ones?
