Question about start of period

[Cricket0619]

I started spotting last Fri. and Sat. ( light spotting but dark brown in color) and got my period full on sometime during the night and had actual blood Sun. morning. When should I chart that my period started? I originally took it as my period came late and now I am wondering if Fri. was when I should mark down that it started. TIA

If you went to bed on Saturday with out red flow, and woke up Sunday with it, I would mark Sunday as CD1. If you didn't need more than a pantyliner, then the spotting should not be counted as your period.

Agreed with pps. Day of first heavy flow.

I count as first day I need a pad or tampon. Not spotting.
