elevated liver function?

At my 20w appointment I mentioned to my Dr that I have been having a pain in my upper right abdomen (gallbladder was removed 3 years ago), like right under my breast/ribs. She palpated and said she wanted to test my liver and something else I can't remember. She also said it could be reflux or indigestion and recommended I take Zantac 2x/day. They called me back today and said my liver is slightly elevated? Sending me for addition lab work. She said it normally comes back as nothing but wants to be cautious. Also wanting to do a CBC, and a hepatitis screen? That word really scared me. Anyone else go through this? I am freaking myself out.
