Could these be signs of early labor?

The past two days the baby has hardly moved what so ever. I've had menstrual cramps, and lower back pain pretty frequent, my discharge has changed, I've been experiencing round ligament pains, constipation, and I've felt pressure down there but only a few times and sometimes I feel like I'm tearing down there... any suggestions? FTM so a bit worried. My ob told me since I lived far away to go to the er and get checked but I don't want to go up there and them say you're fine and me feel stupid... also I have felt her real low, she doesn't feel as high as she was a couple days ago. Btw I'm only 30 weeks.
