Thanks again all. Trying to read through all of the comments!
I ended up asking the health visitor about it today as she asked if I had any general worries, so I said well nothing in particular other than the labour and birth.
She was nice and did make me feel a bit more at ease, talking about breathing techniques.
She echoed what a lot of you have said, with try and stay at home as much as possible where I'll be able to distract myself for a while with watching TV, snacking etc.
She wished me a short and easy birth, ha ha! If only if was that easy 
Tinymeteor - I'm also feeling a bit
about having a needle in my back (not scared of needles in general though?!) but I'm sure in labour I won't be thinking about that!
I'm just generally a bit scared of any intervention they may have to do 'down there' 
makes me squirm a bit thinkingabout it!
Rosieliveson - another thing I've been panicking about! What if I actually can't physically push anymore!? Would anyone believe me?!
VeryPunny - yes that's what the HV said to me today, to 'keep an open mind' about it all. Although I don't think my mind could be any more open, I'm overthinking as it is! 
Roastpots - glad it's been useful for you too. RE food, I think someone mentioned like yoghurt drinks/smoothies to me as they feel quite filling. Echoing what someone else said, probably through a straw would be easier. I think I'm also going to pack lucozade, ribena cartons, crisps, some sort of breakfast bar, and maybe some dark chocolate for the iron.
Bonkers - I do hope so!
TiedUpWithString - How awful that you weren't properly informed. Although my HV has said to stay at home as much as possible and obviously people do recommend it, I think I'll probably ringing them up with the first contraction!
Mumofsnotbags - thanks for the after-tips.
Still some very contradicting stories so it definitely proves that every labour and birth is different! 
I suppose it's impossible to ask for advice when you just really never know what it's going to be like for you!
Thanks everyone I appreciate the help
