Back pain and Braxton hicks are vrry encouraging!!! You might be surprised just how almost ready your body is by Monday!!!
Last Monday I went to hospital to be induced at 39 weeks due to GD. I had had lots of Braxton hicks and back pain over the previous 3 days and was so hoping to go naturally over the weekend. Monday morning saw me 3cm dilated so dr broken my water and left me to see if labour developed on it's own. Alas after a couple of hours only mild contractions were present. Due to my GD I had to be on an insulin infusion so when they connected that up they also gave me syntocin.
My midwife was a women in her mid twenties Stacey and she was great. Even though I was connected to 2 drips and a hr monitor for bubs she helped me be as active as I needed or wanted to be. She also explained about syntocin and it's use in first and subsequent pregnancies. In my hospital the dose of syntocin for second and subsequent pregnancies requiring induction for any reason is half of what is given for first pregnancy as your body has been there before and knows what it is doing as such lol. The aim is to have no more than 4 contractions per 10minutes otherwise you are considered to be overstimulated. The dose of syntocin can be increased 1/2 hrly but mine was done hourly and only twice as my body was getting the hang of things without too much help. They also only check your progress internally every four hours and it was less than that for me when I told them I had to push lol. I had to pant through one contraction while the doctor checked me lol. One minute I'm telling the poor man not to touch me and then I told him to bloody hurry up and check as I didn't want to hurt me or bubs if I wasn't dilated fully. I was dilated enough and next push presented her head and the rest of her came with the second push. VERY QUICK
Second induction was very different from first. I wouldn't say one was worse than the other they were just different. With both I had no pain relief by choice although it was offered. I hate the thought of an epidural so I prayed everything went fine so I wouldn't have to have a csec!!!
I'd be getting a second opinion as your BP is only slightly elevated possibly from stress by the sound of things. Perhaps come to an agreement that you won't got further than 41 weeks...
Best of luck - for natural labour
