Intense pain at37wks

I can barely stand, I can't walk or talk through contractions, have to really close my eyes and focus on breathing. 3-5min apart super intense accompanied by bleeding went to L&D last night tuesday morning at 1am where I was sure I was in labor or atleast close. They monitored me tried to say I was only 1cm when I got there and left when I was just checked early Monday morning and was told by my doctor I was 2-1/2 ish 3cm I was given fluids to see if it would help settle the contractions and it didnt, i was told to pee and it didn't work to settle contractions they didn't give me any kinda meds to help with pain when I asked and ended up puking from the pain about 4am and was sent home told to take 1000mg of Tylenol for pain... im absolutely hurting all over, I can't sleep, eat, or get comfortable with the intensity and frequency even with the Tylenol. What should I do?
