Itchiness in toe -20 weeks pregnant

Initially I had itchiness in my toe during early pregnancy. Later it raised to upper part of leg. Very itchy during evening & night time. Even if I apply moisturizer, it feels itchy. I thought it is a normal pregnancy symptoms. But later read an article in Asianparent that itchiness is because of serious illness with the liver. Should I consult my gynae or take home remedies?
