Labour near?

I'm 37 weeks today and for the last couple of days I've had braxton hicks that come and go(not sore and very irregular) but last night seemed to be getting more regular however they have now completely stopped, I usually always sleep through the night however last night I woke up 4 times, today I feel nauseous, tired and I also feel like I need to poop but when I go nothing comes out and I have already pooped this morning(sorry tmi) could this be labour getting close or is this usually how you feel bearer the end of pregnancy?
