I have been watching my discharge as my OBGYN advised me to do, I went through the changes of discharge when I was suppose to be ovulating. But now my discharge has went back to being creamy right before my period. I’m experiencing sore breast, some sort of pressure feeling in my lower abdomen, and nausea. and my period is due in 5 days. Can someone tell me why, this is the first time this has ever happened to me.
