Clear Blue Advanced - missed peak


Hi all,

Just wondering if anyone has had a missed peak using the Clear Blue Advanced.

I’ve had peaks before on these & had a chemical pregnancy in early April.

Usually 34 day cycle & have had high fertility since CD 14.

I got a quite strong line on cheapie LH strip on the evening CD 18 but not quite positive. I tested because I had sharp, one sided, transient pain. Could I have peaked overnight?

Currently CD 21 & no peak on the Clear Blue & cheapie strips getting fainter.

I had to get routine bloods & low & behold, I’ve ovulated. I’m relieved that I did but so much money wasted on testing.

Has anyone ever experienced this?
