Pregnancy question plz help!?

Ok im 39 weeks preg& my due date is monday. I went to my doct appt yesterday ( i was having conttactions that morning) and i was 1 cm dialated& fully efaced. They did normal chk up n sendt me home. Ever since then i have rreally bad cramps it hurts to lay & walk. I cant sleep. N i woke up at 5 a.m n threw up and had diaherra. I called the doct n they said to cme in & he'll check me but my water hasnt broke & i get sharp pains but not constant contractions. I dont want to go & just get sendt home. && the nurses n doc will look at me so dumb n just tell me its normal. Wat should i do? Is there a chance theyll induce me? Any advice??
