I would really really want to tell my Mom asap, but I would rather do it in person - hard when we live in different towns. I'd tell most people straight away - if anything goes wrong I'd want their support anyway. My biological father I don't know what I'd do. He doesn't bother much, hasn't come to see me in over a year, but it would still be his first grandchild. Dunno. Maybe wait and do something dramatic like sending a scan pic in a card.
