Werid symptoms

Did anyone get any weird symptoms when they were in labor? I have been feeling off all day, like anxious but not Anxiety and having to feel like throwing up but not throwing up. I'm not nauseated or have "Moring sickness" I just feel STRIGHT up werid. I'm 39 weeks exactly today and when I went to the hospital 3 weeks ago I was having contractions and The midwife I seen at the health department said I was in labor. My mom was telling me how some Women either get really tired or feel sick/off when their body is prepping them for birth/labor. Anyone have this? Or any other symptoms? Let me know!
