36 weeks feeling extremely weird


So today was my baby shower. But let me tell yall I am beyond exhausted. I came home around 8:00 showered and I an trying to rest. However I cannot handle this back pain and wont stop throwing up :/ idk i just feel odd.. baby is moving good. I just feel so dizzy and nauseous. Is this a sign of labor. I am scared that I may have done alil too much. Thats my little family below. Please comment It was a bit too hot today maybe that could of done me wrong.
