Can morning sickness come back in the 3rd trimester

So I’m 29+4 and in the mornings I have been waking up a little nauseas but then it’s passing but this morning it continued I was going to go to the gym and for a walk but I just started feeling worse and worse and my lower back is also hurting so thought it wasn’t a good idea to push my self so I drove to nona so she could help with my son while I laid down I ended up power chucking and then laid down for a little while again got up for just a plain cracker and some water and instantly threw up is it normal for morning sickness to come back in your third trimester i was really sick at the start up until about 14 weeks then it passed I didn’t have my morning sickness come back with my first so not sure if it’s normal?
