Nausea before labor starting???

I’m 35 weeks pregnant and I have felt great up until now. Sunday I woke up just feeling “off”... I was cramping and just felt exhausted and nauseous so I just took it easy. Well today I’m still feeling nauseous like I could throw up and I’m having loser stools but I haven’t eaten anything out of the norm or anything... And I randomly started having hot flashes....

Has anyone got really nauseous and just rough feeling before they went into labor??
