When is cd1 exactly?

[coracle]

I tend to have a couple of days of very faint pink CM before AF really arrives. Should I count the first pink cm day as cd1, or the day AF really shows? The pink cm is not all day, just once or twice in a day.

Thanks

The first day of true AF. Pre-AF spotting doesn't count.

Thanks Whitney!

(OT) I love the name Wisdom!
