37+1, latent labor for 3 days, NO progress

Every 12 hours since midnight on Tuesday (5 episodes) I've gotten strong contractions that last 2-3 hours then abruptly stop. This is my sixth baby and as advised by my doctor, I've been drinking red raspberry leaf tea daily since 34 weeks, applying evening primrose oil to my cervix since 36 week, drinking pineapple smoothies daily since 34 weeks and staying active by continuing to walk my other kids to school daily (it's about four miles total per day) So after days of these 'episodes' I just got home from my regular OB apt. Hooked up to the ecg machine for 15 minutes I had two contractions. Doctor checked me and I am still not making any progress at all! Not effaced or dilated at all! She said she nor the hospital would do anything, including a membrane sweep, to move things along! She would however give me a prescription for TYLENOL to help ease the pain so I can get some sleep! I literally cried and had non stop streaming tears.
