I confess I feel a little superstitious about the pregnancy - I feel that if I tell people the baby becomes less real (maybe I wanted to be pregnant so badly that I tricked the world into believing it). Which is ridiculous but I'm not always entirely rational.
Church on its knees helped a bit because Father Dave talked about God has control over his plans and will take them through to completion and then I was reminded through Ps 31 to make God my refuge (and the point was hammered home in John 15 "Abide in my love"). It's a bit easier to panic though.
