I had noticed some blood in the toilet for about a month but thought it was due to constipation. I was working fulltime and have four children to look after – being so busy I just carried on and didn't dwell on it. One morning, however, I thought I had diarrhoea but all I could see was a lot of old blood in the toilet bowl. I left my husband with the kids at home and took myself straight off to hospital.Staff at the hospital found evidence of bleeding with no obvious cause. The doctor said he would write a referral to a specialist for an urgent colonoscopy.
