I just defecated a while ago. And as I was done, I noticed that there's something red in the bowl, when I took a good look at it, it looks like blood to me. My last bowel movement was 4-5 days ago. I have had this kind of defecating pattern since I ca remember, but sometimes I pass stools everyday.I have many assumptions for this. It could be my period or it could be because I have eaten a lot of red foods today. I do not have abdominal pain at the moment, but yesterday I had low back pain, but it was just a sec. I have been diagnosed with gastric ulcer before. What could possibly be wrong?
