Should I be worried?

KD

This is my first baby I’ve carried full term and gave birth to so I’ve never experienced a period pp. I’ve been told by many that it comes back full force and is really bad. I got mine 4 days ago and it only lasted 2 days, wasn’t heavy just regular. I know everyone is different and that they can be unpredictable but is it something worth bringing up to my dr or nothing to be worried about at all?
