Nausea @ 36/37 Weeks..?

I’ve never had nausea during my pregnancy, but I’m experiencing it now..

I’ve heard vomiting/diarrhea/nausea are the cases of getting closer to labour..?

I don’t know much as I’m a FTM, but I need reassurance.. My next appointment will be on Thursday.. Plus I’m getting induced @ 38 weeks due to health issues and that the baby’s underweight..

What did you experience before labour..? Like, did you go through nausea, too..? If so, how long after did you go into labour...

Thank you and I appreciate any help..
