You can eat any HARD cheese when pregnant -pasteurized or not. The warnings are only against soft (un-aged) unpasteurized cheeses.
"Eat hard cheeses instead of soft cheeses: The CDC has recommended that pregnant women avoid soft cheeses such as feta, Brie, Camembert, blue-veined cheeses and Mexican style cheeses such as queso fresco, queso blanco and Panela.
Hard cheeses such as cheddar and semi-soft cheeses such as mozzarella are safe to consume. Pasteurized processed cheese slices and spreads such as cream cheese and cottage cheese can also be safely consumed. The most important thing to do is read the labels! "
