Too soon?

I’ll be 14 weeks tomorrow. My cousin, more like a sister wants to throw a brunch so I can announce to our family. We’ve had 3 deaths within two years, so this is really exciting news. I’m also the youngest grandchild thus the last to have a kid. I feel really nervous. Is this too soon to be announcing? I don’t have a super close relationship with my family, she does.

I know they’ll be happy. I think. Should I just go ahead and do it?
