I'm sorry op. It should be a national scandal and it isn't. As someone who has suffered birth trauma, i wish id known the following in advance.
Research as much as you can about what options end risks are acceptable to you, and put them in your birth plan, then make sure the staff know - for example if you really, really don't want induction/forceps etc and would rather a C section, if any of those things look likely, you may need to put your foot down. Obviously in an emergency that goes out the window but chances of an emergency seem lower if the mother is treated with respect and listened to. I prepared and researched but they didn't listen so:
Be prepared to strongly advocate for yourself. Make sure your birth partner is someone who will stand up for you, and question things if you can't. If your partner is a quiet mouse who you know wont speak up for you, consider taking someone else.
Ask plenty of questions.
Go prepared with food and drink for yourself in your hospital bag.
The chances are everything will be fine but make a plan, talk it through with your midwife/midwives before you go into hospital and once you're in, make sure you understand all of your options and what risks you are most happy with and then be prepared to stand up for yourself. It's awful that the last needs to be said but that's the state of the NHS.
