Sorry new to this. When do you say ovulation has happened? when you get a peek on an opk? Or when you get your first postive, when the test line is as dark as the control line? Or is is the following day? Want to know how many dpo I am or will be. The app says I ovulate tomorrow, But my afternoon test today was negative. I think I would have gotten my first positive yesterday had I gotten the test earlier. My tests just came in the mail today. This is my first time ever taking opks. Thank you in advance 😁
