I had two post-date inductions. One medicated and one not. I can tell you my story and if you'd like to chat more feel free to PM me. Prior to the inductions here are the things I tried:
EPO (this will not put you in labor, it just helps prime the cervix)
Sex (see above)
4 hours of daily nipple stim
Red Raspberry Leaf Tea
I take EPO orally my whole pregnancy and then vaginally starting around 25 weeks. That is aggressive but I am/was desperate to avoid an induction. If I were you, I would see the chiro and acupuncturist NOW, consider orally taking EPO, start your RRL tea and put the rest on the back burner until 37 weeks or so. At that point consider your options, talk to your practitioners and go from there. Maybe they'd be against the cohosh but ok with the Castor oil. Against the Castor oil but no the enema. Whatever. I got daily membrane sweeps with my second that might be an option for you as well.
Now my medicated induction took HOURS. I mean, like 50+ hours. I credit the fact it ended in a vaginal delivery to PATIENCE, and the fact my midwives were willing to unhook the pit at night. I was able to shower, take an Ambien and get some sleep. I want to say I had a four break every night but I can't be certain. Regardless it was heaven. They kept me well fed, well rested, and laughing. If you do end up with a csection at least you know you tried. You can look back on it and KNOW you did everything anyone could under your circumstances. If you go straight for the c/s, I'd worry you'll spend your life wondering if you missed the chance at a vaginal delivery "Maybe my induction would have been successful? Maybe I should have waited." I also have friends who blame every respirator infection their children get on their csection. Unfounded or not, it's hard to reason with Mother Guilt. If you end up with a c/s that was going to be the out come if you skip the induction anyway. You may as well try.
The key is to make sure you are well rested, well fed, and have realistic expectations. Make sure your doctors understand that once they plug you in you are starting at 0. You didn't have the luxury of having days of prodromal labor, or the night or two or indigestion you blamed on the Chinese buffet only to find out 27 hours later it was labor starting. Expect an induction to take days or hours although it might not. If they aren't willing to let you eat enough, have someone bring you food. INSIST on the unplugging at night, my second night there I had to really fight for it. But in the end my wishes were what counts. Sure it would have been nice to have my baby 8 hours sooner, but that sleep, I am certain, is what kept me going. I don't see how I could have had the stregnth to push otherwise.
Don't set yourself up with expectations of unmanageable pain, contractions on top of one another, horrors! I know plenty of people, myself included who didn't have that with pitocin. I labored naturally for three days- watching movies with my husband. Eating Olive Garden take out with my mom. Playing cards, checking my email, etc. It wasn't how I envisioned my birth, but it wasn't a horrifying nightmare of a birth either. I was sorry to have missed the birth center, but I wanted a healthy baby, a vaginal delivery, and no regrets/informed consent. I got all of that, and that's what matters. I was treated respectfully, wasn't separated from the baby, and released to go home as quickly as possible. Some people have terrible experiences with pit, some don't. Just stay positive and assume you'll be in the "don't" category.
With my second, I had a good pocket of fluid under the babies head. They broke my water and prepared for me to need breast pumping (I was refused an induction because of "macrosomia" blagh) but instead my labor took off like a shot! They broke it at 6:30am and my baby was born at 8:18am. If I end up post-date again this is my plan. I'll do all of my Stuff that I do to try to stick to term (I am already seeing the chiro and accu), have them break my water, and then resort to pit if it comes to that. Keep in mind there is no reason that couldn't work for you too. You'll have to see what your Bishop Score is, how dilated you are, babies positioning and all of that. But it can and often is done!
Hell, you may also naturally go into labor! You never really do know until after wards, eh?
