Thank you john, molly, and marc.
I just came from the toilet to do my business and my poop was perfectly formed and the color has gone lighter (yellow green-ish). I did wipe with tissue paper and the color was yellowish-green. Sorry TMI! No black spots or whatever.
I just wanna ask:
1.) Was that a good sign?
2.) What does one mean by tarry? I've googled "tar' images just to be sure, but I get images of tar in different colors and consistencies. Is it that one that is sort of like thick semi-liquid and sticky and jet black?
3.) If this were something really serious, shouldn't I have more symptoms like fatigue, constant stomachache, vomitting, etc.?
