Pregnancy Announcement Questions..Helppp!

Sa

We are 7 weeks pregnant today. March 5th will be our second ultrasound. When did you announce your pregnancy to parents/family? Was it in a group setting? One by one? My grandpa (dad's dad) is having his birthday party March 11 and my whole family will be there. I really want to announce then but 1) this day is about him, not us 2) it's a little sooner than I wanted to announce 3) I still want to do an announcement for my dad beforehand (which puts us announcing even earlier). And let's not forget my mom and her side of the family AND husband's parents/sister. Do I do something special or just let word get around? We originally wanted to announce on Easter but the only family that's getting together is the husband's 😕! Any input will be much appreciated! Heeellppp!!!!
