<s>[INST] I drink a lot of monster energy drinks, id say too much a day. I just went to the bathroom and... well there was blood in.. stool. I dont know if its from energy drinks or something but im very scared. This is the first time this has happened. It was red but nothing red wiped up. I looked online and i wasnt eating red food. I dont know whats happening. My stomach hurts a little two like cramps but im not having a period either. Please help me. [/INST] Hi.The simple test of urine will help to confirm the bleeding and other infections. Also needed is an ultrasonography . If the urine has an infection, please go also for urine- culture and sensitivity test. Once the sample is sent for lab test start an antibiotic suitable for urinary infection. Consult an Urologist. </s>
