Congrats on your upcoming delivery. 🎉 I had a medicated birth on my first and currently 37 weeks planning a hopefully unmedicated birth this time round.
I feel a lot more prepared for it this time because I've accepted how much it's going to hurt. 😂 I've been working on my mindset for it, that it's completely temporary and my pain isn't stronger than I am.
Also preparing my partner for verbal affirmations, how to help position me to reduce pain, how to advocate in medical situations, how to provide counter pressure, how to apply a tens machine, etc , he's had a labour crash course in the last few weeks.
I also have a lot of things prepped to try in the early stages - more as distractions than anything. E.g. comb, aromatherapy, winner flow breathing device. I don't think I'll have the ability to want to deal with these in active labour though.
I would say don't get too attached to a birth plan - e.g. you might not get the water birth and have a back up plan just in case. I've written down my preferences for each scenario I could think of in my birth plan, including section if it's needed and that actually helped my mindset a lot.
If you do get an epidural, knowing how to prevent this from stalling your labour is important. E.g. lying on your left side, or reducing the dose down so you can be on all fours. Using a peanut ball, et c.,
Best of luck with your labour! Totally doable to do it unmedicated if your will is strong enough but either way you'll be so proud of yourself once you're holding your baby.
