    Thanks for posting the question. I was wondering the same thing. I used an OPK just for fun today (D12), and it has a lighter line than the control one. This means is negative, but again I have not done it daily to know yet how the color will change. I wonder how early before you ovulate, you can get any line at all? If anyone has an answer, I’ll appreciate it.

    I’m very confused too. They look equally dark but I’m not sure if that’s a positive or if I should still wait until it gets super dark.

    I think OPKs are positive if the test line is as dark as or darker than the control line. When I used them, most of my positives were about equally as dark as the control. If you’re still confused, and you have some money to burn, you can invest in the OPKs that give you a smiley face. No questions with those ones 🙂
