Oh and another thing, with Vitamin A it is ok to have it in the regular doses but exceeding the RDI can be dangerous to your unborn baby. Vit A is important in your daily diet and you don't need to deliberately avoid foods with Vit A in it , just don't take a multivitamin or tablets that carry high doses thats all.

I think some pregnancy vitamins still have Vit A in them but at safe levels.
its hard to avoid it altogether in your daily diet.
Good Luck
