I was similar to you re pain. I reacted badly I’m also small hipped and just small in general. Reacted badly to gas and air ( vomited down the nice student doctor’s crisp white shirt and tie while we had a chat).
But, had an unplanned epidural, ventouse delivery, with a tear on on perineum but it healed very well. From discussions with friends my birth was probably the best for me and my son.
I’m no natural birth convert and do not believe pain is ok in birth, ( I had midwives being cross with me for not wanting to ‘experience’ childbirth) . However I get others see it differently, it might be a natural process but I was terrified even after being induced and my argument runs that no one has their appendix out without pain relief.
The whole drugs issue re childbirth is contentious, but quite frankly if people want to be martyrs let them. Ask for decent drugs, insist if necessary. I believe there is a cult of letting women suffer in childbirth, it’s not ok, it’s not ok for the baby to have a mother who is traumatised by the birthing process, but understand my view is seen as prehistoric
Do what is right for you. Demand, ask and seek, I get there are pros and cons to ECS, drugs etc etc but the wider picture is happier less traumatised Mum easier transition to bonding IMO.
Also please be aware as you get to full term your fear will subside a little, but it was real for me and as unpopular as my opinion is the drugs worked and my boy was very healthy, if small. I birthed alone and saw it as a medical procedure to bring my boy into the world with as little fuss, and with the best outcome for both me and him.
Please just demand what will work for you.
