I've been on the pill for a couple of weeks now. I started the pack when I was on the first day of my cycle and had a normal seven day long period. I've had no other issues with the pill (was sick the first two days but that passed), but I woke up this morning to some bleeding. It's lighter than a usual cycle and it's lighter in color, I can't call my Dr. because it's the weekend... Has anyone else had this?
