It's not positive until the test line is as dark as or darker than the control line. You are looking for your peak. Download the premom app and scan your tests in as it will help you identify peak. Then when you've found it you will likely ovulate in the next day or so.
Thank you ladies will do!
I’d recommend downloading the Premom app, you can load all your tests in and it’ll log them and tell you if low, high or peak. I would start from after your period ends and test twice a day. For it to be positive the test line needs to be darker than the control line.
