I can tell you that as someone who can't have children, I LOVE it when my girlfriends are pregnant. You can celebrate with them and you also recognize how special the experience is. Enjoy your friend who has stuck around, because you know that she will likely be there after the baby is born and you need to talk with someone over 3 feet talk

As for the rest of them, it is their loss. You are going through an amazing process right now and you will meet alot of new people during the next few months, many of whom can relate very well to what you are going through.

But having said all that CONGRATULATIONS!!!
