Cramping... is this normal?

Bre • 26 - Married - Early MC June 2017 - Rainbow Baby May 2018🌈💙- Due again March 2020

I had a MC 6/23. AF was due yesterday and I've been cramping for 3 days now. Still no AF. It's the worse cramps I've ever had and they are like really really low, unlike when I have cramped before it's a little higher.

Had this happened to anyone? I'm wondering if i should go see my doctor or wait it out.
