You have gotten some great feedback, and really, you need to do what is right for you! Know your options, the risks and benefits of both, and listen to your heart. If a VBAC is really what you want to try for, then finding peace in the unknown and embracing your patience should be your mantra! Often times the constant uncomfortable at the end of a pregnancy is a sign of labor on its way!
There are so many benefits to letting the baby choose his/her birthday regardless of your chosen delivery method. To help keep you comfortable until then, I encourage you to see a chiropractor and an acupuncturist. Both can help to relieve discomforts, help get the baby in an optimal position, and even use gentle techniques to get labor started. If you aren't doing yoga, checking out a class or two, and notifying the instructor of your discomforts can also help you make simple adjustments to relieve pain and prepare for labor.
Also, there are a number of things you can do at home to help encourage labor to begin...stay relaxed, and let go of stress and expectations, warm baths, massage, relaxation practice. Sex and nipple stimulation, or simply romantic cuddles, kisses and caressing...anything to boost your oxytocin and reduce adrenaline. You can also check out some herbs HerbLore.com has great information and products and Pam is a wonderful source of info and support and EPO orally and/or vaginally.
I wish you an empowering and blissful birth and peace in making the decision that is right for you!
