Why is my body doing this to me??? HELP!!!!!

So Monday I went to Triage, said I was 3 cm dilated but wasn't having strong contractions so they sent me home.

Wednesday went to Dr. appointment and they said I was 4 cm dilated and 50% effaced! I was like sweet!!!

Thursday I call out of work due to contractions. They came and went every 5-6 minutes and then slowed down to every 10-15. Get to triage, per my doctor, they observe me for an hour and say I'm in the early stages of labor and send me home. I lost mucus plug and had more bloody show from then to Friday.

From Friday to now I've had inconsistant, STRONG contractions and I am just miserable! The amount of pressure in my vag and butt are makes it excursiating to walk....and we have tried everything to move things along! Sex, pumping, walking, yoga ball bouncing, warm showers, tea....and nothing! I walked 2.5 miles today and have nothing but sore hips and an aching back to show for it.

HELP!!!!!
