Anti-biotics in labour by drip are a pain but you are doing the right thing to research now. It could make all the difference to your experience.
You need a midwife who knows how to support active labour and anti-bs.
You will likely be augmented (induced once labour starts). I had strep B and you have to go in to be induced as soon as your waters go.
This means an epidural (induction hurts like buggery without) and things like water birth are out.
I'm not trying to scare you! I'm trying to give you the info you need so you can prepare.
I wasted loads of time at ante natal learning about managing without drugs through water birth - I wish someone had said - look, induction can really hurt, you will almost certainly need an epidural, water birth / midwife led unit is no longer an option.
I also wish I'd known what questions to ask about continuous monitoring.
My antenatal classes were all about how active labour is better / less painful and being on your back was bad.
Then I found myself in labour having continuous monitoring with a MW who wanted me on my back so it was easier for her to monitor me. I didn't want to be on my back and felt totally unsupported.
I wish I'd understood this. I would have read up on continuous monitoring, asked the MW at the start if she preferred me on my back for monitoring and if she said yes asked for a different MW while I still had the strength to put my foot down.
