What is considered cycle day 1? Is it when you start spotting whether dark brown or pink or is it when its bright red, full flow?

In brief: First day of menses
Cycle day one is the first day of your menses, and normally it will be full flow and bright red.
In most cases women will not spot prior to their menses with dark brown or pink flow. That is more common at the end of your menses.
