What in the world is happening?! I had 5 days of high fertility last week (testing on CB advanced digital opk). I got my peak on Saturday the 23rd. And I believe that means I ovulated Sunday. So I am 4DPO. Today, I tested just out of curiosity and got high fertility. What does that even mean?

Am I going to ovulate again? Or is it possible I might have implantation?

Anyone else experience this?
