Spotting vs Period

For those of you with regular cycles, do you log spotting as the start of your period?

For example, I had two days of spotting, mostly in the morning and before bed and then a heavier flow today along with that crampy and overall feeling of blah. Should I log those spotting days as period days? Or make today the start of my period?

I’m trying to get an accurate prediction for when we start TTC in five months :)

TIA!!
