I had a planned section with ds. It was a really good experience for me. I watched a few videos of seconds from some positive birth platforms and read up a lot and envisioned it and that all helped me feel quite prepared in terms of what to expect.
I went in that morning early and did a covid test and then we were waiting to be called (it felt like being at the airport). We were first up because of my diabetes so I'd bring something with you to distract you. I made a playlist for the birth during that time for example.
Then we were taken into a ward and prepped for the surgery. The anesthetist will come and meet you and talk you through everything and answer any questions and you get a gown and stockings. (Bring slippers and a dressing gown because it's open at the back and you need to walk to the theatre) then they went through my birth plan with me (I'd suggest doing one for your section).
Went into the theatre, everyone introduced themselves and what their role was. There were about 8-10 people so quite a few but all were absolutely lovely. You sit up on the bed and try to bend over and arch your back out as much as you can. The anesthetist will give you a numbing injection first (I used my hypnobirthing breathing from this moment on and it helped me stay calm) and once you're already numb then they give you the spinal injection. I remember it being more uncomfortable than painful. I needed it done 3 times because they didn't get the right spot and when that happened I got like an electric shock sensation ran up my back (made me jump a bit but nothing drastic) I'd read that could happen so I was prepared for it which helped a lot. Once they get the right place it doesn't hurt, you just feel a heat starting to spread and then you need to lie back on the bed quickly before you lose control. It kicks in really fast. But they talk you through every single step so you know exactly what's happening and they will go at your pace (I'm terrified of needles and they were very reassuring as I'd noted that in my birth plan).
They then check that it's worked by using an ice cube to check your sensations. And then when they know its all OK, they insert the catheter and put up the curtain and get you prepped. They didn't actually let my dh in until first cut was made I guess because they want to make sure everything is going smoothly before they add a new person to the room.
No pain whatsoever, just feels like someone is moving around in your tummy it's strange more than anything. The anesthetist will sit up beside your head with your birthing partner and talk you through what you're feeling and hearing and generally try to distract you. You can start to feel sick when the anesthesia kicks in but they will just monitor that and adjust it which helps immediately so you just tell them exactly what you're experiencing.
It was super quick, I think it was about 10 minutes from first cut until ds was out screaming. I was fully prepared because sometimes babies born by csection need a bit more help with breathing.
Then they placed him straight on my chest and closed everything up. As they were finishing they took dh and ds out into the recovery room and they got skin to skin time which I was cleaned up etc and that took about 5/10 mins. Then I was brought into recovery and we got our golden hour and I was helped to breastfeed before being moved to the ward to recover an hour later.
You've lots of choice, you can choose to have music in the room (I'd recommend it, I forgot my music and after dh and ds went out I wished I'd had it) you can ask for the room to be dimmer/quieter as baby comes out. You can ask for them to be given to you before being wiped down and weighed etc. You can watch them coming out, ask for delayed cord clamping, what happens to your placenta and what you want to happen if you can't have skin to skin immediately etc. I'd focus on trying to build a birth plan you feel happy with because it makes you feel more in control. And bring snacks for when you're back on the ward!
It was such a lovely experience for us I'd not be anywhere near as nervous going in if we're lucky enough to have a number 2!
