There are other ways your doctor can look for the cause of your enlarged liver. He may use an ERCP, a scope that checks for problems in the ducts (tubes) that carry bile. An MRCP, a special type of MRI, also helps spot that kind of trouble.
Cholestasis of pregnancy, also known as obstetric cholestasis or intrahepatic cholestasis of pregnancy, usually occurs during the last trimester of pregnancy, and triggers severe itching, especially on the hands and feet. On rare occasions symptoms may appear before the third trimester.
Certain medication can darken your stool during pregnancy. One of the popular over-the-counter medications Pepto-Bismol, prescribed for stomach upsets, often causes dark stool in pregnancy. For such reasons, before taking any new over-the-counter medication during pregnancy, consult your gynecologist.
