Morning sickness - pregnancy symptom or just a fluke?

Claire

I am currently cd17 which should be way too early for symptoms, as far as I know. Glow estimates this cycle will be 28 days, though my last cycle was 24 days, so who knows! this cycle we started ttc on cd10. I have no idea when (or if?) I have ovulated but the thing is, this morning I felt super nauseous and threw up, I’m not sick, and I rarely throw up as is.

Is is possible that this could be pregnancy related? Or is it waaay to early to tell?
