Period question!! :)

MamaJ
So this month my period came a week early. I experienced light pink spotting for two days, followed by a heavy period for two and a half days..now suddenly my period vanished!
​I usually have 4 period days and no spotting. Is it normal to have a 2 1/2 day period? And should I count the spotting days as part of my period or the first day of normal flow? Thanks y'all!
