False labor?

Friday night i was at the hospital for some contractions and cramping. I was there for 4hrs and given turbline for the contrations and put on fluids. My contractions seem to be back along with tge cramping, so i decided to call the hospital and ask if i should go in. Its been almost and hour since they started i am 30weeks along. The nurse who answered, i explained everything from my last visit, said i was given turbiline because i had been to the hospital too many times and that i should count again and drink more water. I have drank 3water bottles today. Contractions havent sstopped and seem to bee getring a little stronger along with the cramping And now this nurse made me feel like a cry baby and like im annoying them.
