OP, I was in an antenatal ward for nearly a month with my last (5th) child, due to a complication.
On that ward, we watched every single induction and they left them up on the ward for ages before transferring them down to delivery. After a while, us old lags would bet on how long their labours were. The panicky ones seemed to go on much longer...
One first time mum came in the night before with her husband, and we could hear them going on and on about "The Book" and how they were going to insist on this, and make sure they got that... We saw The Book was some massive NCT tome.
The next day, she was induced and several of us (not first time) mums had to hide our laughter when she said to bloke "It's not like it said in The Book"... Too right, mate. It really isn't.
When I had my first kid can remember on the ward the day after, some women were being shown round as part of their antenatal classes, and one poked her head round the door and asked us all "What's it really like?" The woman next to me said to me quietly: "Shall we tell her?"
We decided against it.
No books and words can prepare you. People say a first labor might be 16 hours. Mine was 67 minutes. And not particularly terrible, if I'm honest. I later had good labours and bad ones - one was 21 minutes. Another a mighty 2 hours. Oddly, the longer ones were the easiest as it gets in a kind of pattern. Also the fast ones are too fast for pain relief and have no discernible 'stages'.
My best advice comes from my own experience and observation of lots of women going into labour over that month I had in the antenatal ward... Be gung ho. Be fearless. Go for it. The women who seemed panicky or petrified really did seem to have far longer labours. I dunno if any midwives have noticed this? A lot of it is out of your control but some of it isn't.
FWIW my best labour was the longest because they had time to get an epidural in. I was actually having a cup of tea as I gave birth to my 3rd kid, so effective was the pain relief. I had several other kids with no pain control. Because they knew I laboured fast and so wouldn't let me even attempt it. One of my kids was delivered into the bare hands of a midwife who had been having a coffee break, and refused to believe I could go that fast. Student pulled her back into the room and she didn't get time to pull on her gloves. About a second before I had said I was about to have the baby and she said I most definitely wasn't. That taught her. ;o)
