Question for mamas

Beth
Hi all, so I'm 35 weeks along and the last hour or so have been feeling super crummy. I'm a first time mom so I need some advice-  I'm not sure if it's just a fluke or if I should be more concerned. The baby is moving a ton, my stomach keeps getting pretty tight, and I'm just really uncomfortable. I also feel almost feverish, but without the cold part. Just really warm and uncomfortable. Any not first time mamas out there that can help me out? Braxton hix? Am I just maybe getting sick?
