telling my grandparents I'm pregnant

Lindsay
I am currrently 5 weeks pregnant...I know the rule is 12 weeks, but with my family I don't want to shy away from telling them because they are so close to me....I really want to share the good news....
My hesitation is that I had a miscarriage a few months ago after I had already told them...and it was hard for them to deal with....but I still feel like I should go ahead and let them know again this time.....thoughts?
