Mine wasn't traumatic... Although maybe not straightforward.
Woke at around 3am with an urge to run a bath! Halfway through the bath running felt quite wet so checked underwear and found dark green discharge.
At 4am decided to phone the the maternity unit and they told me to come in via taxi - I may have had some pains by that point but can't remember.
I told them I was on my own so bad a bit of a 'discussion' with them and they agreed to send an ambulance. Had pains in the ambulance but nothing more than period pain type stuff.
Got into the delivery suite, I was sure the baby was "right there" (my exact words) and the midwife scoffed saying I couldn't even be completely dilated yet. She checked, her face went white and she said he was indeed right there!
My blood pressure dropped at one point,obviously baby was distressed hence the meconium, they talked me into Pethidine which spaced me out terribly and so I couldn't really push, so they had to use the ventouse and give an episiotomy.
So yes, intervention but from early labour to birth it was about 3 hours so in the grand scheme of things, I'd say not too awful?
I was at the shops the next day with the baby (I was a single mum) so can't have been too bad, lol
