Is there a way to know for sure that you ovulated with Billings since there aren't temps to confirm? Can you reach a normal peak and dry up without ovulating? I been using Billings for 6 months now (used STM before) and never had an issue before.
I'm 7 days late based on my usual LP but I got a BFN when I tested 2 days ago. Is it possible that I just didn't ovulate?
Thanks for any advice
