I too think it couldn't hurt to look into if there is an independent midwife that you might be able to speak to. Or maybe make an extra appointment with a midwife at the hospital.
Are your education classes run by the hospital? Put your hand up and ask questions.

One very important thing is maybe try and make an appointment with one of the OB's at the hospital. If you are high risk they are the ones who will be making the decisions. Best to suss them out now so you know what their opinion is, then go do some research and make your own informed decision.

Maybe consider a doula to help with the liasing once labor begins. Or your support person should be informed of the options and your wishes too.
