I googled ' "Vitamin A" in utero' and found this (http://www.gghjournal.com/pdf/volume_12/12-3/ab11_12_3.pdf).
It's a report of research specifically about Vitamin A consumption in the first trimester, and suggests you might want to avoid going above 4x the RDA during that period, at least if you are consuming your Vitamin A in pill form. This (http://lpi.oregonstate.edu/infocenter/vitamins/vitaminA/), on the other hand, says your RDA while pregnant is actually a little higher than in daily life.
The safe limit, just assuming the worst about dietary Vit A because I'm too dozy to read properly, seems to be about a pound of liver a week, during early pregnancy, anyway.
