Back in early Sept I had constipation with odd mucus and blood for two days. I had take Amatripllin day before and stopped 3 days later. Ever since I have had 15/18 days with no constipation then hits me intermittently. Since I have had two really really tiny bits of blood in clear mucus (put toilet paper prior to stool) it's normally more after a few days of constipation. Have done 4 FIT tests, 4 Calprotectin and Lactoferrin all normal. Doctor examined me did bloods all normal has referred me although may be a long whole before I'm seen. I'm 37 not overweight don't smoke or drink, diet could be better. I do take 2 blend drinks a day off fruit and veg but do drink 6/10 cups of tea a day. I know I'm at lower risk due to age but still worry about the deaded C word. Blood last two times is so so tiny almost as thing as a hair. Wondering if constipation was caused by cancer surely would be constant more blood etc? Have put on 5 pounds no weight loss at all. Anyone had anything similar?
