This is the first cycle I have used OPK's so it is all new to me.

I have tested the last 3 days, and yesterday I got a negative but it was darker then the days before. The time I have been testing is 2:40pm.

Due to it being darker yesterday, do i still test at that same time again today, or do I test earlier or later?

I am only doing one test a day and am using confirm.

Thanks heaps
