I was GBS + and my mw suggested a membrane sweep. I too had read the same thing about it not being a good idea. I brought it up with mw and she disagreed. I have to trust my mw more than dr. Google.
I think you're doing the right thing to educate yourself. This way you can ask your dr/mw why this way and not that way? What are the risks and benefits? What happens if we do nothing? I am no proponent of inductions but there are medically necessary reasons to do them and they're a lot of different ways to do them.
Ask the mw/dr what is the med necessary reason for suggesting induction?
Really educating yourself and having a dialogue with yr provider is the way to go. I write down my questions before hand so I don't forget or get confused. I ask questions in a manner that I hope is respectful. I expect to be talked to in a respectful manner that answers my question on a level I get.
Knowledge is power!
