I’ve been using the clear blue advanced digital OPKs for the last 11 days and I’ve had 8 days of high fertility with no peak fertility result. Does this mean I haven’t ovulated? Is it possible that I ovulated without it showing up on a test? I have had ovulation cramps but no other symptoms. Should I see a doctor?

DH and I are getting a little tired and I’m worried that I’m not ovulating - I have a very long cycle at 40+ days and this is my first time using OPKs
