8DPO and nauseated

8DPO and in our 7th month of trying. Had some nausea two mornings ago and then this morning on the way home from work and this afternoon when I woke up. I do tend to get nauseated when I'm over-tired (I work midnights) but feels like maybe it's something different. Then again, I could be symptom spotting just like every other month. AF is due in a week so we'll see what happens. Not feeling super hopeful at this point but who knows.
