Preterm labour signs? Sorry long post

32 weeks pregnant was In Hospital Monday due to reduced movements even though they didn't pick up many movements on monitor they were happy with heartbeat however they did mention there was a lot of contractions nothing was said other than if they become painfull to come back in. So still getting a lot of Braxton Hicks, pelvic pressure and very bad back pain and 3 day of diarrhea, I don't feel like eating I just feel drained and uncomfortable now. Do you guys think this is labour signs?
