Pregnancy announcement delay

Hello all, 
I was wondering if anyone else's is waiting to tell their family they are pregnant? 
I had a miscarriage a few months ago at 4 weeks and I had told my family about that pregnancy. Then when I lost the baby I felt like I should have waited. Now I'm 7 weeks pregnant and I still haven't told my family. I'm waiting till I get my first ultra sound done then make sure everything is fine first in order to tell them. I'm so nervous right now my ultrasound is next week :)
