Unlikely. It is unlikely that pregnancy caused it if you had no problems during the pregnancy. Pregnancy can be associated with HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets) but this is a very serious disorder which can be fatal to both mom and baby as can acute fatty liver of pregnancy. Both would have been diagnosed during pregnancy and indicated delivery at a high risk center.
