Okay, under full disclosure, I JUST starting using OPKs last week, so I don’t really know what I’m looking for. I’ve read the instructions and used Dr. Google but I thought I’d get opinions from you ladies.
I am using OPKs twice a day starting on CD8. My test instructions say to use FMU, even though many people say that is not the best. So, I have been testing with FMU and then once in the evening. On my OPKs, I have had a very, very faint test line every day and I know that is considered a negative test. Then, this morning with FMU I had a darker line that was almost as dark as the control line, but still not darker than the control line. The instructions tell me that it is a negative unless the test line is darker than the control line. Is this always the case, though?
Thanks in advance!

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.

@candy11: Yesterday my test line was slightly lighter than my control line (which is when I posted this) but this morning it was darker – yay! So I do think it gets darker as you get closer to the LH surge that it detects (which means you’ll ovulate shortly).
To answer your question, you’re supposed to ovulate 12-48 hours after you get the positive, depending on how close to your LH surge that you took the test. So, basically, if you get a positive test, get to 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 🙂
