Hi Kati, I'm so sorry that you're going through this after everything you've already been through to get here.
I would try bathing in epsom salts to allow your blood pressure to drop slightly- if it works, great, if it doesn't then what the heck. That's one of the few things you haven't mentioned trying yet. I'd also get very very in-depth and personal with your doctor- what's the VBAC climate like over there? If it's not great, you really need to get this baby out of your yazoo by whatever means.
Some things you need to know: epidurals lower blood pressure. This is one of those circumstances where I am saying, with total blinding seriousness, take the drugs.
The ladder of interventions put you at greater risk of infection, one way or another, because you may end up with a c-section or episiotomy. Start yourself on vitamin C and zinc now to get your immune system at top-notch now- thinking about it, actually, I'd take probiotics as well.
If your membranes remain intact, the induction can be stopped at any time. Once they have been artificially broken, Poppy really needs to be out of there within 18 hours, one way or another.
On breastfeeding: Poppy is likely to maybe need a little more help to get the hang of it than she would have done if she'd cooked till 42 weeks. Don't take the pacifier, you don't need it and it could set up problems later on. Get her to your chest immediately, don't allow routine separation for observation, and keep her close and feed her lots. No supplements by mouth, especially not formula in a bottle. You ideally need a side-car bassinet for your hospital bed to keep her close whilst letting you get some sleep.
Finally, I'd read Birthing From Within. It helped me a lot this time round, and it helped ease me into a gentler frame of mind. I know people have found it helped them let go and accept that birth is a miracle, regardless of how it unfolds and who you accept intervention from
Oh, on natural inductions: there isn't anything other than acupuncture or homoeopathy that I would consider safe enough for someone whose blood pressure is high enough to require medication, and you need professionals for both of those. I did do ginger compresses that last week with River, though, and it felt good (fresh ginger steeped in boiling water then placed straight on my bump.) Castor oil is horrible and the cohoshes weren't much better, plus didn't actually get the baby out. My vote is take the pitocin and the epidural.
