Should I go to L&D?

Today has been one of those days where I have been feeling crappy. Barely any sleep, lots and lots of pressure, cramp like feeling at my lower pelvis, one of the twins is either kicking or punching my cervix like trying to come out, lower back pain, tightness in my belly, and now I feel it at the upper part of my stomach near the top of the uterus. I am 32 weeks and concerned. I was trying to keep them in till 36 weeks which is November 17th but I'm worried they are trying to come sooner and I really dont want them to and end up in the NICU. Should I go?
