Telling family..

LJ • 1 baby girl with another baby on the way
I'm 5 weeks pregnant. I had a very early miscarriage just before getting pregnant this time. At 4 weeks and 4 days. 
​I always said I would wait until my first scan around 12 weeks but I'm finding it so hard to keep quiet :(
​How do I stop myself from telling?
​And when did everyone else tell their family?
