Why is my daughter at 8 half months pregnant getting yellow very loose stools,she has been like this for about 2 weeks,?

Jaundice: Yellow discoloration of the skin is worrisome for a problem in the liver. Infection, blockages in the biliary tract can do this among many other conditions. Your daughter needs to be seen by a physician as soon as possible

Loose stool. : That often happens as labor approaches. Think of it as preparing for labor. It doesn't sound worrisome. If in doubt, talk to her obstetrician.

Infection?: She could have an infection from food or a GI bug, or this could be due to diet changes or just the pregnancy. She will need to see a doctor to be sure. Good luck!
