currently in L&D waiting to be seen

I'm 27 weeks. Had intense lower abdominal and pelvic pain that gradually got worse within the last 24 hours. I was scared I was in preterm labor so I came in. The nurse asked my symptoms which are: irregular bouts of intense lower abdominal and pelvic pain, diarrhea, very watery CM, nausea.
She asked me if I knew what SPD (Symphysis pubis dysfunction) is. They have me hooked up to the monitors and this pain is excruciating even laying down. 😓 
It even hurt to poop but I had to. Anyone have info on preterm labor or SPD while I wait? Loving and thankful to hear my baby's heart beat at least. ❤️
