Short period after stop breastfeeding

Hi!

Normally my period last 8 days counting those with some spotting. But this month it came same day it wast suppose to, but just lasted 3 days. First and second day heavy and the third light. And stops completely. I was breastfeeding my lil baby for 16.5 months but around 3 weeks ago he stops wanting to be breastfeed, he is drinking regular milk already. Do you think my period is shorter because of the stop of breastfeeding? TIA
