Confused

So Glow guessed my period would start Monday the 6th. So when I woke up I was having some mild cramps, took a shower and went to the bathroom and had light pink blood . Throughout the day my cramps got pretty bad but hardly was bleeding. Tuesday came and cramps weren’t as bad i was bleeding a little more but only had to change my pad on time the whole day. Then Wednesday I had no cramps and spotting every now and Then with light pink blood only when I wiped. So I guess my question is could this be me just having a weird period? *note my periods are usually 5 to 6 days bleeding heavily
