Elevated liver enzymes?

35 weeks pregnant. I got a lot of blood work done last week after having the stomach flu, and the doc found that my liver enzymes are elevated. I've had the tests repeated several times and they're still elevated, but leveled off a bit. My platelets are fine so the doc doesn't think it's preeclampsia, but she doesn't seem to know what it is. 
Anyone have elevated liver enzymes? How did your doctor treat you?
I'm supposed to go in on Thursday but now I'm worried that I should be seen earlier or that this could be something serious.
