Vegetarian pregnancy

Hey ladies! I just found out that I am 5 weeks 3 days pregnant with my first baby!  I have been a vegetarian for 8 years. I am concerned about getting the correct nutrients for my baby. I have never had an issue with getting proper nutrients, but a baby changes everything. Is anyone else a vegetarian that is pregnant? What should I ask my doctor? Would it just be easier to add some fish or chicken into my diet a few times a week?
