Nausea, frequent bowel movements and feeling off

Kristina • Kristina

I'm 38 weeks and 4 days along, I'm 1-2cm dilated and 60% effaced. Today I have been feeling very off like something is about to happen, I'm currently still nauseous but have been for most of the day and have had frequent bowel movements. My question is does this mean labor is near or imminent? And did anyone else experience this before labor started and how long before? TIA
