Is it normal to still have cramping almost like period cramping 4 weeks after giving birth?

I’m not bleeding anymore, but I’ve been cramping & sometimes notice a little odor, but not always.

I’m worried I may have an infection or something but I don’t see my dr for my 6 week check up until April 13.

Thoughts?
