Is this normal or is labor soon

So lately I've been pooping so much more than normal also have had bouts of nausea and I've vomited a few times also been shaking and having some Braxton hicks... I'm 36 weeks 5 days with my second. My first pregnancy was smooth hardly no pregnancy symptoms at all and this one I've had just about every single one so all these symptoms I'm having are new to me because I never had any with my first
