Faint OPK control line...

mrsj0423

I am using Answer brand cheap OPK's.  I have been testing multiple times a day because for about a day and a half the test line was as dark but not darker than the control.  I thought I might try and see if I could catch it when it was darker so I could be 100% sure.  Then today I tested and the control line was much lighter than it has been.  I also saw a test line and it was lighter than the control so I am pretty sure the dark lines yesterday were my positives.  I dipped a second strip in case the first was defective and it was exactly the same.  I was just wondering if anyone else has experienced their control lines getting lighter and if they knew why.  My only guess would be diluted pee.  Any thoughts?

You can only compare the test line to the control line on the same OPK. The darkness of the control lines can vary from test to test.

Yeah, what I meant was that I dipped another stick and the control line was as light as it was on the first.

Could be diluted urine, Could also be that you were gearing up to O and didn't, or you could have O'd already and just missed your "darker than the control" postive result. The only way to confirm Ovulation is with a temp shift. OPK's just tell you when your body is working it's way towards Ovulation.

If your test line was AS dark as the control, I believe that counts as positive. I think the rule is AS dark OR darker.

Sorry - I misunderstood your question!
