Hello Everyone I have been diagnosed with IBS. I have been impacted twice and the second time was my choice worse. I wasn't really able to use the bathroom and when I would go it will only be little floating pellets with blood in them. So I went to the doctor she gave me some medicine to make me use the bathroom. So everysince then I've had mucus in stool , diarrhea, and sometimes chronic constipation. But tonight I noticed something different. I went to use the bathroom and my poop was like yellowish brown with dark dark brown or black streaks covering parts of it ? I have been vomiting a lot and I read that excessive pints of vomiting can cause it but I'm wondering if it's something I have eaten. I've eaten Taco Bell twice this week. And I'm wondering if itslike lettuce Bc it kinda looks stringy like lettuce but just dark in color. I'm scared and my anxiety is going up. What should I do. I'm scared if I go to the doctor it's something much more and ten times worse. I'm only 20 yrs old and I feel discussed by my own body.
