opk /ovulation question

[comet1234]

Hello this is my first month using opks I test twice a day (2&8pm). Yesterday and today's 2pm one had faint pink lines which the ones before them were blank apart from the test line. I'm on cd 12 and I'm usually a 30day cycle. Would these be counted as positive and should I bd or will they get darker...

Thank you!

The second line needs to be as dark as the test line in order for the test to be considered positive.

the lines need to be the same or the test line needs to be darker than the control line to be positive
