For the past few days I ve had noticeable blood in my stool. However I don t see any obvious blood until it is in the toilet and the water starts to turn red. My stool is back and very creamy. I m feeling very tired but otherwise not in any noticeable distress. my lower abdomen feels crampy at times and almost like a dull ache. I m 43, I ve had no heath issues in my life. I m very healthy- I run many miles and/or work out every day for many years now. Cholesterol is low. The only thing different is when my birth control pill was renewed, I m now getting the non generic version of Apri. But took the generic formula for 1 year. I just started the new non generic version Sunday. Not sure if its related but its the only new or different substance I ve introduced to my body in quite some time. I m still very hungry as usual. Several days this week I did notice my urine darker than usual and I thought it odd since I drink a lot of water. Not sure if I have a small form of internal bleeding?
