Spotting or cd1 ?!

So yesterday I started spotting light pink and brown

As the day went on it turned into a darker pink colour

Today I’m still spotting, some pink and some red.

None of it is heavy flow or clots, I’m also not cramping or moody like my usual period.. i have the odd twinge / pain here and there in my back & ovaries but the fact some of it is red coloured I believe it most likely is my period starting..

I’m about 9dpo (don’t track due to stress) ..

should I consider it my period early and class myself as CD1 as of yesterday.. or do I wait for full flow??
