Can someone help me please, so I took a clear blue ovulation test the 10th day into my 30 day cycle as that’s what it stated on the pack. It stated that I was at my peak for fertility so obv done the dead.

I updated the app and stated I took a ovulation test that stated peak, so it changed my period date which I know is not going to come on that date , as my periods have been regular for years.

Anyhow question is when can I take my test when the app says or when I know my period is ?

Also app was not accurate with my ovulation. It was a week late.
