39 & 3days

So around 3pm today I started getting contractions (period like pains in abdomen and lower back ache) they were about every 5-6 mins apart, it's now 11:00pm and I'm still getting the pains ? I tried a lukewarm bath,changing position and drinking fluid. Nothing is working ! I'm getting aggrevated ! I stop keeping track of the contractions but they seem to still be about 5-6 mins apart and still the same pain. What should I do ? The last time I went to the hospital they just pumped me with sugar water and sent me home since I was still only 2cm dilated ... ? I don't wanna go all the way there again to hear them say the same thing 😔 please help I'm 3 days away from my due date 😬
