Clear Blue Adv. Digital Ovulation Test

Keep in mind that I’m using Clear Blue Advanced as you read this:

My last period was 6/29-7/3.

The digital test displayed a chance of high fertility between: 7/10-7/14 and I piqued on 7/15.

Then, the digital test displayed low fertile days on: 7/16-7/19

And then on 7/20 the test displayed high fertility.

What does this mean??

My projected period is expected on:

7/27

I’m worried that there is something wrong with me.

Any feedback would be deeply appreciated 😊
