Cramping and first AF?

KDee • Tried for almost 5 years, with every test and almost every fertility procedure, until I finally started telling the doctors which tests to do. Hoping this rainbow baby makes it and stays!
It's been 36 days since I started miscarrying and went in for my D&C. For the past 3 days I've cramped worse than I normally do but still no sign of AF. Did you guys cramp before you started your cycle? How long before? I have never wanted my period to start so badly! I feel like until it starts, I'm just in limbo. I'm just hoping these cramps are a good sign.
