My period is being weird

Demariss • 29 year old wife and mom of 3 👶🏽👧🏽👦🏽

I am currently in month 5 of being off the pill and so far all of my periods returned to normal except this cycle. I took a test two days before my period was due and it was negative. I have been bleeding but very very lightly and my period was due the 17th. Not sure what’s going on, because my periods were never like this before. What do you think???
