Thanks SCN, for clearing that up. I didn't know the difference. The day before it was lighter than that then I took this test but it never got any darker. It got lighter each day and then 4 days after that af showed. I don't remember it being abnormally heavier. Since then my cycles have gotten longer and last month I didn't ovulate. I did this month and I think my cycles may have shorter finally thanks to Agnus castus, but we shall see.
