While clearly at least some women can self induce with herbal B&B cohosh, my own experience and that of many other mws and mamas is that it is not the most reliable way to induce, and can have toxic side effects. It seems to work better to augment labor than to start it--and Blue C. works well for pph.
Castor oil would probably be better, IMO.
But what you do depends on a lot of factors...are you having any warm up labor yet? What is your history of giving birth, weeks-wise? Or, if this is your first, what about female family history--on both sides of baby's family? Because some women just take longer to cook babies, and this can run in families--and because baby is also involved in providing signals to start labor, you have to look at the father's female relatives as well.
Yes, YOU are the boss. If you don't want to be induced, simply refuse to show up for induction. It is your right. If you want to make nice with your care providers, then offer to do non-stress test and/or biophysical profile to help reassure that baby is still doing well. And then wait for nature to take it's course, which it eventually will!
