It might be too much to digest at this stage of your pg but I had the Mayes midwifery textbook when I was training as a mw, and it's excellent. There's also a lot of YouTubers who have been happy to film their labours, if that's something that would help you. You can search for home-births or active labour as that's a couple of options to narrow the search for videos.
There was a birthing doctor (obstetrician) called Michel Odent, he said births should be in a quiet, soothing place for the woman to feel calmer and comfortable. His approach is worth a look.
By now your baby should be head down (but check with your mw) and you might start to get Braxton Hicks contractions ("false" labour-like pains) any day now as your body practises for the real labour later on.
You might be getting more heart burn and it might be easier to get sleep propped up a bit in bed as your womb takes up so much more room.
Soon you'll get "lightening" when the baby's head starts to decend further into the pelvis and it becomes a little easier to breathe.
You might get your "show" (mucous plug) a week or so before the labour begins, but not necessarily.
If your waters break- or you think they have call your mw unit as you need to go in after 24 hrs to prevent infection. Your waters might look yellowish and smell a bit like semen (sorry! Just so you know it's not just a bit of pee). They might leak out rather than a movie-style gush.
There's three main stages of labour.
The main push-breathe bit is when you actually get ready to birth your little one, then you deliver the placenta. (Either contracting "naturally" or they will give you a drug to get the placenta moving)
Also, you might poop a bit in the last stage of labour, it's nbd and is a sign the baby is almost out.
Like I say, look into active labour, also plan your pain relief options. Do you want drugs/gas and air etc.
This all depends if this is a low risk pg etc. Only you and your mw team will be able to make these decisions.
You might go overdue with your first, in which case there's a few options - a "sweep" of your membranes, or a drug might be needed, an induction. These are only for information, hopefully the baby will just come when they are ready.
Hth. Sorry I can't think of everything (I have baby brain myself!!) Good luck I'm sorry if it's not helpful but wishing you well
