I am 32 weeks pregnant. i normally have a healthy brown stool, occasionally a runny tummy due to ibs and lactose intolerance, today i have experienced 4 very light clay colored stools. is this cause for concern?

Doctor can evaluate: Grey stools can mean a liver or gallbladder problem. If bile from the liver or gallbladder doesn't mix with the digesting foodstuffs inside the intestine, then the stool can have a grey color. A primary care doctor or Ob-Gyn doctor can evaluate, and will likely order some lab tests. He may refer to a gastrointestinal specialist if needed.
