Nausea and hot flashes 35 weeks pregnant?????

I'm an FTM and don't know whether what I'm feeling is normal. First trimester had awful morning sickness and since the second up till now it went away but today I felt like I'm going to vomit again. Also hot flashes returned(had them in the first tri as well). My body aches, my lower back is hurting pretty bad. Is this normal at 35w+3d?

Also, how often can you get Braxton hicks at this time?
