so conflicted!

So my God father wants to have me, my husband, and my sisters over for dinner this week. He asked if we like sushi, and I undeniably love sushi. However, I'm 6 weeks pregnant and have no idea how to handle the situation. Do I tell him I'm pregnant before everyone else? Or avoid the raw sushi? Even if I told him it would have to be through text or phone call because of the distance which is definitely not preferable.
