Labour soon? Or just sick?

Did anyone else feel sick before they went into labour? I just got done working on the Baby's room like 45 mins ago. I came and laid on the couch to prop my feet up and then all the sudden I started to not feel the best. I felt like I could throw up instated to get really hot my chest hurt a little bit. My mom cooked us all dinner and I can't even eat it becuaue I feel sick to my stomach. I have very light cramping on the sides of my belly next to my belly button. And a little bit underneath my belly button. Its just very very light cramps. I just feel exhausted all the sudden where I want to sleep. Also for the past 4 days iv bad a Bowel movement everyday and I usually only go every couple days I'm 34 weeks and 2 days. Has this happened to anyone else all of the sudden?
