So my cycles are 26-28 days long, and af lasts 3-4 days. I’m super regular and today is CD 28 for me with no sign of af showing up... my question is, has anyone been on the day they were supposed to start and didn’t start. But instead spotted light pink only when wiping a couple of times ? If so, could that mean af is about to show? That’s never happened to me right before starting. It usually comes on full force. Any advice?? Tests have been negative so far, except for one that looked like a vvvvf positive
