Spotting or Period how to track?

Ok. I’m trying to track my cycles as accurately as possible because I am TTC. I have been trying to find the correct way to log the information in the app and also for future Dr appointments. I came off the pill in February.

I have regular 28-30 day cycles. But my menstruation lenght and flow has been a bit weird. So, I’d like to know how would you log this info:

I usually have 2 days of spotting. The bleeding is super light, not enough for a pad. Maybe a liner

Then, I start my full flow, which I consider my first day of period. It usually starts light, to where I only need to use about 2 regular tampons a day.

Then it gets heavier for about 2 days, and then I have the very light spotting again for about 2 days again.

Should I consider the last 2 days as light bleeding? And part of my menstruation length? Or not?

If not, my period would be 3 days, which I think its quite short.
