firstly congrats
and in my book that i've got from the midwife's here it says food to avoid (its a long list) :
unpasturised milk and products containing unpasteurised milk
liver products and vitamins containing vitamin a
raw or partially cooked eggs
cheeses like camembert, brie and any blue cheeses
pate
raw or undercooked meat (steaks etc have to be well done not rare or medium rare)
fish like shark, swordfish and marlin
raw shellfish
alcohol
undercooked ready meals
you should also wear gloves when gardening or changing cat litter and wash your hands really well after handling any pets
other than that folic acid and prenatal vitamins are really important ... in the uk (dont know where u r) u can get something called pregnacare ... thats got everything u need in it
if u want to know anything else feel free to PM me and i'll try and help ive got loads of books on pregnancy so should be able to answer ur questions lol
