I need help deciding CD1

Hi! So ever since I got off BC in November, I consistently spot 3-4 days before I actually start. However it gets tricky around day 4 when it turns more into a very light all-day flow rather than spot. It’s so light it doesn’t leave a whole lot on my pantyliner, but there’s a lot more when I wipe than your average “spotting amount”. So today was that kind of day, every single time I went to the bathroom it was very much period-like but so so light. And right now before bed, it seems like even more and brighter red. Now by tomorrow I know the floodgates will open, so I usually claim tomorrow as day 1. But should today be considered day 1? I’d say yesterday was definitely more “spotty” than today. What do you think?
