Period with less blood. Help!

Ericka

my period this month has beign light, i usually get heavy ones, but this months i would say it has been 60% less blood, i started spotting and then stop for like 2 days and my "period" started and i am scared, i barely need to change my pads, or bleed at night, yes, the blood is red, but i am worry, i am 28 and never seen something like that. I'm not pregnant btw.
