Is this normal?

I'm 31 weeks. I'm having nausea and diarrhea. I'm having contractions but they're not painful. I can feel my stomach tightening. It started yesterday and they're still not painful. My LO is moving around A LOT. I'm having increased discharge that seems to be watery. I can't count my contractions because sometimes I can't feel my stomach tightening and yesterday I was barely able to eat anything. My next doctor's appointment is June 27th. Are these normal symptoms or premature labor symptoms?
