OPK question..?

[heychrissie]

Hi all, I took an opk test yesterday at 7pm where the test line was nearly as dark as the control line; today I took one at 2pm (admittedly with a lot more urine - yesterday's I had just enough to do the test tilting the cup, today had a full cup) and the line today was much lighter. Is this to do with time of day not being consistent, more urine/dilution or have I just missed the LH surge? Today is Cd 12. Should I test again later? Thanks!

Could be any or all I'm afraid. If you have enough tests I would test again later and make sure you BD just incase!
