Any more suggestions? NEED HELP!!

Im due Monday. Have had my membranes swept x2. Spent hours on the ball bouncing and rocking, sex, walking, squats, steps, warm bath and tonight wild wings. Been 1.5 cm dilated 3 weeks. Went to hospital last night with contractions every 4-5 min but they wouldn't take me because I'm not dilated. They said cervix was still very long. Was given a shot to stop the pain and came home. So frustrating. Today I have had some contractions but not as bad and close as yesterday. Had an ultrasound and found out I have an anterior placenta with a grade of 1(not sure what that means) any suggestions on getting the ball rolling??
