I have had diarrhea for two weeks, pregnant for 5 months, I’m waiting on stool samples to come back. No other symptoms, I have had chills and sinus/head congestion since October, but the diarrhea is new. I’m eating very bland, no gluten no dairy no sugar, there are pieces of undigested food in my stool and now when I wipe after a bowel movement there are black specs but the bowel is not black - can someone help me
