My best advice would be to think about what it is you need when you are stressed and anxious.
Inadvertently did something close to hypno birthing with my daughter. Closed eyes imagining I was on a boat in the ocean and my breaths control the waves. It is something I learned a long time ago to manage when life feels overwhelming. I need slow measured breaths to settle the waves.
I labour best on my feet swaying at the hips. I had my first at 38+6 after my waters went the night before. I was fully dilated when I arrived at hospital. I had been in 2h early for be assessed and had only been 2cm, I was given 2 paracetamol then. Once I was in hospital I got straight into the pool that the midwife on the mlu had run whilst I travelled over and had some gas and air for the pushing stage. Baby was born in the pool within an hour of getting to the hospital. Moments before he was born the midwife had pushed the emergency button however as it looked like her shoulder had gotten stuck so she was born to a rush of drs running into the room. Thankfully the shoulder managed to free itself. I had 4 stitches for slightly worse than a graze. The midwife said they were mostly for " cosmetic" reasons what ever that means. I had some diclofenac before the stitches and nothing after that.
I had my second in September. I was called in for induction at 36+6 as my health was suffering and there were real concerns that I wouldn't be well enough to give birth. I had extreme fatigue where I couldn't be awake for more than an hour or so and was sleeping over 20h a day, I had poor liver function, Obstetric Cholestasis and query HELLP, as part of this I had low platelets so I knew this would mean I wouldn't be able to have an epidural. I had had 3 admissions already, couldn't look after my daughter or myself and had to stop driving. The thoughts of my medical team were that an uncomplicated vaginal delivery would give me a better recovery given my physical health but a straightforward c section would probably give me a better birth experience given my physical health. We made the decision to start with an induction but have a low bar for switching to a caesarean. I only needed the pessetry in for a couple of hours to get me into labour. Whilst I was on my feet I laboured ok but I could only be on my feet for half an hour before having to have a nap. After about 12h I no longer had the energy to stand and my labour went backwards so they made the decision to break my waters for me, this accelerated labour as it was my waters that was keeping the head away from the cervix and with my having to lie down there wasn't the pressure from baby to break the waters. Baby went into distress and they lost his heart beat three contractions in a row. They did another exam and based on that they made the decision to keep going as they felt I was very close to delivery. They unstrapped the monitor and had the student midwife chasing baby down my pelvis during contractions which allowed them to monitor him better and about 20 minutes later he was born. He had the cord wrapped tightly around his neck and was born blue with heavy bruising. This was the cause of his distress. By 5 minutes post birth he had perfect scores. I had two doses of paracetamol during the induction process and gas and air only for the delivery. I had some paracetamol and ibuprofen immediately after birth and no other pain relief. I had a graze but needed no stitches. Calm breathing got me through again. The water made the birth of my daughter better but the induced birth of my son was easier. My daughters labour was quick and from the start the contractions were 3 in 10 minutes with not much let up. The contractions with my son started at 33 weeks as I had an irritable uterus, I had a sweep at 36+6 to see if that would trigger labour which it nearly did and probably contributed to not needing the pessetry for very long. The midwives were amazed at how much I was able to sleep on just paracetamol!
I stuck true to me, I don't like candles and smelly stuff, I don't like fuss and mantras. I like closing my eyes, shutting out the world and getting into a head space where I feel like it's just me. Before my first labour I asked my partner to help me make decisions for a calm birth as much as possible. For the second it was about conserving my energy and hoping my body could find some reserves from somewhere. I was fortunate that things that could have gone wrong didn't, if my daughter's shoulder had become dislodged on its own, if my son's heartbeat hadn't recovered or if the midwife thought delivery would be too far off I would have ended up describing very different labours.
My sister had an uncomplicated water birth but as her baby came out arm first she had a really bad tear that she had to be moved to theatre to have stitched up.
We write birth plans and think of birth as a binary decision when really it is many decisions and often it's a role of a dice whether it is the right decision or the right outcome. Don't get too fixed on particular things being helpful or unhelpful. Be open to suggestions and yes think about what keeps you in a calm headspace
