Fish/Sushi & Pregnancy

Brittany • fearfully&wonderfully made.
A friend of mine is going out to dinner on the 17th for her birthday: I'm not sure yet if I'm pregnant, I won't find out til this weekend or after. She's going out to a Habacbi grill, I would happy with rice and chicken, but whatare the rules when it comes to sushi/fish during pregnancy. I feel like there are so many opinions out there I thought I would ask here!
