Pain after D&C

AF is due today for me.  No spotting yet.  I have been cramping for almost two weeks with most pain on my left side and had severe cramps yesterday for about an hour with a temp spike to 99.8 and went back down to 98.6 a couple hours later?  This is unusual for me.  I am not sure if there is something wrong.  I had an mmc and needed a D&C on 1/24.  This would be my 2nd AF since then. My first AF was painful for the first 2 days, which is normal for me except the pain was more elevated.  We were TTC this last cycle, but i didn't have all this pain with the last pregnancy and tested negative this morning. 
Anyone else experience something like this?
