Hi. I have recently started getting tummy cramps. This turned into blood in my stool 3 weeks ago. Since then I have had blood in my stool (mainly darker red), worsening cramps on some days, diarrhoea occasionally, an increased need to go to the toilet and normally I have a fragmented or stringy poo, much more bloatedness and gas, funny noises in my tummy like something is moving through it. 

There is no consistency to the symptoms and on a few occasions I seem to have had a properly formed poo with no blood in it. 

I have seen my go and had blood tests done. The results were all normal other than a slightly higher C-reactive protein. My lymphocytes were also slightly increased. My stool samples all came back normal. The go couldn't feel anything abnormal on inspecting my stomach or on a digital rectal exam.

the doctor said these test results look good, and I have been referred to an nhs outpatient appointment next week. I am also pursuing an appointment privately.
I am now really frightened that I may have bowel cancer. Does the above sound similar to anyone? How long does it take to have a colonoscopy afternoon your hospital appointment? How long does it take to get any results?

thanks
