I guess it also highlights how little I was prepared for DD's birth, and how in shock I was after because I am only know really questioning it because I will have to do it all again.
It's often the way. But you have time now to look into it.

My suggestion is that you get on to a trusted health carer or an independent midwife to access and go through all your files from last time and figure this out. I'm no expert, but my impression is that you were not cared for well, at all.

And, the disjointed nature of care - I mean different people pre/during/post, as is standard for most mothers, unfortunately - means you have to go on a sort of forensic scavenger hunt to actually try and piece it together. Having someone there to help you make sense of it could be really helpful. And I really think that understanding what happened last time will be helpful in looking forward to this time.

I sincerely hope that you have a much better experience this time. The foundation of a good experience, in my opinion (and in my experience), is receiving good care.
