Need some advice... 4 weeks post d&c

Hope

Hey I'm definitely going to call my doc tomorrow. But wanted to know if this sounds normal or start of an infection. My d&c; was exactly 4 weeks and 1 day ago on 8/30. Since Monday I started getting some mild cramps that have been there since then and as of today my uterus feels kind of sore and tender feeling, I've had some creamy cm/fluid but it is not foul smelling. My spotting stopped on 9/16 and we did have sex multiple times since then. I have not had my first period yet and assumed it was going to show by the way I was feeling but hasn't yet. I just feel sore from my uterus to my vagina area. I also don't have a temp. Has this happened to anyone else?
