I am on the pill Sronyx and take it everyday between 8p-9p, never missed a pill. I have taken two inactive pills and on the first day of taking an inactive pill I noticed faint bleeding. It has been a day and it still isn't getting heavier. Usually I start off like this but it's usually getting heavier by now. It is definitely a red color and not brown. I am having all of my normal symptoms that I usually have with my period. Does it just sound like it's taking me a while to actually start or is it implantation bleeding?
