Is there anything I really shouldn't eat?

I am between 6-7 weeks pregnant and I've seen my GP about 4 times, but she hasn't said anything about food and what I should/shouldn't be eating. this is my first pregnancy and I'm unsure whether there is any foods that I should not eat! Is there any really dangerous foods I should avoid? :)
