Nausea and Sickness 36 Weeks

I’m 36 weeks today and I woke up last night with a mouth full of bile/vomit.

I had been sleeping on my side and propped up and only for about an hour before I woke.

Is sickness common at 36 weeks?

I haven’t been sick since but I feel nauseous and I don’t fancy eating, even though I am getting hungry occasionally.
