@PatientBee:  it might be that your body is gearing up to o but for some reason isn’t and it gets delayed. I usually get a progression from lighter to dark unless I accidentally drink too much water and miss my positive.

I didn’t really get a gradual progression towards positive, I would just have negatives and then bam positive one day.  As for your original question, I would say drinking a lot of fluid one day can dilute your sample so you may have had a progression after all and one day’s was just diluted more than normal so it  appeared lighter.
