OPK test always lighter in afternoon?!

Question

I am in my fertile week and have read to test at least two times a day to find my LH surge but, my second test is always lighter in the afternoon.  Is this because of diluted urine?  Anyone else have this same issue??  Thanks in advance!

Answer

This is how mine r looking bottom 3 are today's would you say they were + ? x

Answer

The first test should be with late mornin/early  afternoon urine. 2nd should be early evening.

Answer

I'm literally been avoiding drinking unless I need to until I have taken my 3rd opk of the day usually abt 6 at night and that the lighter one desperate to log my positive opk day testing is frustrating x

Answer

Mine is too. I think it's because I drink lots of water throughout the day!
