this morning i went to the toilet & had a very small bowel movement (due to mild constipation) then around about lunchtime,i went & it felt/looked very watery (no solids whatsover) & i had a slight bit of pain in the middleof my stomach as well..this has been happening on sum occasions for the past month or so,can anyone help?

You probably need to add a fiber supplement to your daily routine such as Metamucil. If this continues though I would see the doc and get it checked out. In the meantime start using Metamucil or a similar product to see if that helps.
