expecting it to be the worst, most painful, experience ever, just wondering if that's about right.
No.
Not because it's not painful. It is.
But because it's a very different pain than you can imagine beforehand. So there is really no point in trying to imagine, and give time to anticipating it.
I'm not into all that visualisation / manifesting stuff. But I expected to have a copable labour, and that I'd make decisions around pain relief at the time.
It's luck, but I'd a straightforward, relatively short birth, found gas & air helpful, and genuinely found it a positive experience. Of course, it's not like that for everyone.
Think positively, be open to change, don't place arbitrary restrictions on yourself (like rigid birth plans or no epidural) and you give yourself a better chance of a labour that meets your expectations, notwithstanding medical emergency and what the baby decides to do!
(My 1st & 2nd labours were fine; my 3rd was very quick but very very hard & painful. You really can't tell!)
