Period-like cramps after period?

Allison • 25 years old, 2 miscarriages in ‘15 & ‘16. Married 💍. 💙 KJS 6/30/18 💙 BBS 4/29/22
My period ended 2 days ago, and it was 6 days long. I usually only get cramps the first 2 or 3 days. Now, 2 days after it's over, I feel really crampy and gross down there still. Anyone else have this happen? What could be going on?
