Labour or just dying

I'm 36 weeks, and the past three days my aches and pains have gotten to about a 7/10. Backache, not so dull. Pelvic pressure almost constantly. What feels like intense hunger pains in my upper abdomen, and achy period like cramps in my lower abdomen. And this lovely new groin pain that makes putting pants on, rolling over in bed, getting up off the couch/chair/bed almost unbearable. No sign of my mucus plug, or leaking fluids. So I figured I would see what you ladies think.

I have my 36 week prenatal appointment on Wednesday, and I'll talk to my doctor about all this fun stuff then.
