Hi

I am a 45-year-old woman who is otherwise healthy for the past four weeks I have had some blood when I go to the loo. The blood is generally bright or pinkish red sometimes just very watery, sometimes nothing at all. Bowel habits have changed slightly. Poo is sometimes a small amount of slightly explosive very soft almost diarrhoea like poo, sometimes small soft Rice Krispie pellets, sometimes perfectly normal shape colour and size but with flex of bright red blood on the outside of the stool. no other pains or stomach problems but HUGE anxiety! 
GP has referred me to a specialist and I've had some bloods taken but no results back yet. 
Any thoughts?
