Cramps/nausea/CM PP

Ly

I'm 11 months postpartum and for the past week and a half I've been having light cramping and nausea and lots of egg white cm. I still don't have a period because I'm nursing. Could this be my body preparing for my period??? Do you get symptoms before you actually get it again??? I'm not sick with anything either its just so random!

Also, I did take multiple pregnancy tests and they were all negative.
