Hi Lala and welcome to the rest of your life!!!
No worries are needed, it's a doddle compared to labour of any length (my son was 73 before emergency C too.) The whole process really takes care of itself if you let it. You shouldn't feel hungry and the time flies by and you emerge like a butterfly at the end. Any problem are not to do with your body, it's your head trying to take over and that's what your LLC, group and us lot are for! We're great at puting you in charge when other bits of you think they should be.
Thanks Foxtrot, I know I can do this! Good to hear I'm not the only long labourer in the world, everyone else I know pops them out!
