Contractions labor confused!!

Latoya • Excited and nervous pg with my son and a mother of an 8 year old daughter
Ok I'm 37 weeks I keep getting contractions on and off I mean stopping me in my tracks hunched over vag and butt pain feeling like I need to do number two. It will happen a few times a hr then stop. He isn't as active as usual...I've even drank something sweet and laying on my left side. I'm aware my contractions need to be more consistent but what is going on ??
