Nausea, could ut just be in my mind?

Im trying not to symptom spot... i dont want to get my hopes up. Im 9dpo based on my cm, cp, and bbt. Temps are still higher than pre ov but did dip a few points of a deg yesterday. I had cramps on 7dpo and a little less on 8dpo. Today more than yesterday.

Anyway. Early this morning i drempt i was puking in the kitchen and since i woke up ive been feeling nauseated. My question..... anyone ever experience nausea like this. Im not sure if its too early for nausea so i wonder if my brain is trying to get my hopes up with symptoms are just residual.
