Hey Nicola851, the above comment as in it may be consipation sounds realistic, however, it could be a number of things!! as in the first thing that sprung to mind for me would be are you by any chance "aneamic" as in low in iron levels because that sounds about right too??? why not go and get a full blood test done if you can and everything can be ruled out!! let me know how you get on okay?
