Hi
Welcome to the MedHelp forum!
Hepatosplenomegaly or enlarged liver and spleen is seen in many conditions commonest being anemia and most likely in your case due to pregnancy. Other causes are leukemia, malaria, tuberculosis, lymphomas, hepatitis, cirrhosis etc.
I think you should discuss these possibilities with your doctor. It is difficult to comment beyond this without examining. A comprehensive investigation is required keeping all the points in mind. Take care!
