Opinions please- telling friends

Really unsure what to do.

So I had an 11w4d scan this morning and all was fine. I live abroad but going back home this weekend so ideally want to tell my friends in person and will be 12 weeks.

I have another scan next Thursday but then don’t know when I will next be home to tell people.

what would you all do? Tell people in person at 12 weeks or wait until the next scan and just tell people on phone etc

Thank you!!
