When did you share the joy?

Just found out one week ago I'm expecting my first baby in October. I'm only 4w3d. I have told my husband and my one best friend, who are both very excited:) I've taken 6 pregnancy tests-all being positive so I know it's true it's just hard to believe! I would love opionions on when it's best to tell your family. It's it ok to tell people you are pregnant before your first appointment? And how did you tell them?! Thanks!
