Good morning ladies!

I am super frustrated. I was pregnant and in March I unfortunately had a miscarriage. We used the advance clear blue Digital. Now my husband and I are trying again. I am trying to use the stick OPKs. It seems that I am not getting a positive. My cycle is 35 days. And I am due for AF on or about the 5th of August.

May anyone assist with information about this? Can I stop ovulating? I am on CD 21, can I still have a chance to have a darker test?

Thank you!
