I have had trouble pooping lately. Sometimes only once in the morning, and sometimes only once a day, but sort of constipated. In the morning I feel like I have to go bad, but the rest of the day there's nothing. I have had a sour feeling in my stomach, kind of like when you eat chili alot. this morning I pooped like a light yellow, this afternoon, I pooped very little like bits and pieces with a tissue like substance almost like a sheet of saran wrap or something.
