Nausea third trimester?

So I was nausea from week 5-10 and then it went away. Haven’t been sick or nauseous since. When I hit 27 weeks I noticed I was feeling nauseous often and like I did during those first few weeks.

Is it normal to get “morning” sickness back in third trimester??? I’m also hot like all the time. I wake up in the middle of the night sweating which never happened before either!
