My trauma with DS1 was related to the midwife not listening to me. I was being moved from mw-led to consultant-led during labour as my BP skyrocketed. On the trolley, in the corridor, I began to push. Not chose to, my body did it involuntarily. She told me to stop being silly, I was hours away from delivery. Insisted I could not be ready to deliver, in the corridor: no checks. So I forced my body to suppress it.
Got to the delivery room to find I actually was ready to deliver, but not only that - that DS1 was distressed (I was later told this was very likely due to me suppressing my pushing). Hit the big red button, room filled with medics, episiotomy and ventouse, and luckily DS1 was born perfectly fine.
Luckily, with fast labour already on my notes (four hours from first contraction to delivery for DS1), I was taken a lot more seriously when DS2s labour began (this was also a big factor in me choosing a home birth for him - was paranoid I'd give birth on the side of the road!). Just goes to show that all midwives (and doctors) need to listen to their patients, not provide care-by-numbers.
My middle sister - with my fast-labours already in the past by then - was taken much more seriously as she could point to 'family history of fast labour'. Hers were the same, 4hrs and hrs. Youngest sister of course, had the worlds slowest labours. Just to be awkward
