Pregnant and family death

Has anyone ever had a family death while their pregnant? I am so scared of hurting the baby. My uncle died yesterday and my dad is taking it so hard and so am I. I am the only person who my dad can talk to who will listen. I have been non stop crying since I found out. How do you handle it and calm down enough to not harm the baby. My family don't know yet. I planned on telling them after my ultrasound on the 25th.
