Baby Announcement

Im 11w5d and have been thinking of ways to do baby announcements with out everyone totally in my business and avoid the awkward "who's the dad" comments and judgment.  Is it better I just keep it between the few close family members and friends who already know? At the same time though I feel it's not fair I can't share my happiness the same way others can. The father and I are obviously not together and he has asked that at this time I respect his privacy...
