Thank you everybody - you're all a fabulous source of information!
Went straight to the hospital and they were brilliant. Took x-rays of my chest and tummy and got me started on an IV straight away. No sooner had the doctor palpated my tummy than there was a small sign of some output but unfortunately not enough to be sure all was well.
They moved me to the assessment unit and started on sips of water. Things finally started to move at around 8pm so they gave me a cup of tea and a sandwich and hey presto! We have output!
Once again, thank you all for your comments and support. xxx
