Oopss I used it wrong?! Clearblue Test

Maybe I am turning dumb?!

I had cramps yesterday and one side was working, so I thought maybe that is Ovulation? I got the Clearblue Digital Test for Ovulation and made a test today midday but it shows an „Empty Ring“ not the 😊 Smiley.

I was sure that yesterday an 🥚has been, but since the test is smarter than my feelings, I must have been wrong.

did I do something wrong?

Or is the test really right?

I always feel ovulation or at least thought I do, now I feel like I am going dumb and dumber 💩
