7DPO - Confusing CM?

Any advice greatly appreciated. I am 8DPO tomorrow. For the last couple of days my boobs have been sore, have felt V. Nauseous. However my CM is all over the place? One minutes it’s creamy & sticky, the next there is nothing. I’m so confused? Never had this before. I was really hoping this would be our month but my CM is throwing me right off 😭
