I've just been having a worry about what cheeses are ok and wrote the Pregnancy Nutrition people at Sheffield.
Here's what they said:
All hard cheeses are safe to eat during pregnancy. The only cheeses that you need to avoid are mould ripened soft cheese, and blue veined cheese. I have attached our cheese list which I hope will be helpful.
And their cheese list is:
CHEESES TO AVOID
Ripened soft cheeses: Brie, Cambozola, Camembert, Chaumes, Lymeswold, Pont L?Eveque, Tallegio, Chèvre
Blue-veined cheeses: Bavarian Blue, Blue Brie, Blue Shropshire, Danish Blue, Dolcelatte, Gorgonzola, Roquefort, Stilton, Stilton spread cheese
CHEESES WHICH ARE SAFE TO EAT

Hope that's helpful!
