Pretty much! Sometimes you will see it start to get darker the day before but it goes from faint to positive pretty much overnight.

I think it may depend on what you buy. I have some urine strips and unless both lines are the same color it is negative. I just started using them a week ago (I had my Mirena removed in May) but AF arrived Sunday afternoon. I am now going to start checking around day 10 until I have a positive or AF arrives.
