I'm kind of nauseous today, which is not something that ever happens. I popped some gum in my mouth and it's too much of an effort to chew it, I'm so tired. And then flavor of the gum (cinnamon) did not help the nausea.

I'm only 4DPO though. So this isn't even possibly an early pregnancy symptom right? Because there wouldn't even be implantation yet for a few more days?
