Third trimester...nausea back

I'm 35 weeks and I feel very fatigue every day after work but I try to calm down and not show that mean face to my husband lol...he would say: why are you mad or in bad mood?! Lol. But now one day I went to the mall and went to the restroom and is smell so bad that I almost throw up but wanted to pee so I left the restroom. OMG! Then I went to the family restroom because it's urge me to pee lol. Now I cannot be somewhere that smell bad/ugly because I almost throw up. I thought the nausea is over lol. I never had morning sickness at beginning of pregnancy. So yesterday night I went to walk and now I feel more tired and body is sore, I don't feel like working today. But gotta be strong for my baby. I'm almost due on May 7th. Anyone had similar situation like no morning sickness at beginning until now?!
