is there any other time in your cycle that you have a LH surge apart from at O?
also when using a OPK, it it best to have 2 dark lines.. or does having the test line darker then the control line mean nothing apart from possible O... ITMS?
ok, from what I know, and experience, the test line has to be as dark or darker than the control, but the darkness doesnt make a lot of difference, as long as it at least matches the control line you are good for seeing the surge. I used to test up to O, and would see it clearly get darker and then fade over a few days... but I would think that if you see a really dark line then it means that you tested at peak surge... good luck. xo
