My confusion came because I thought people were saying that people shouldn't post about their BFPs at all in those threads.
I was thinking, well... I'm in a few of these threads, and as we're all trying to get pregnant then I would love to hear from someone in my thread who 'made it'! I'd hate for them to think that they couldn't tell anyone that they'd got a BFP, and just disappeared from a thread where they had got to know people and been supporting others.
I think I get what you mean though. Sounds as if people are saying that announcing the BFP is okay, but going on about the pregnancy after that is not okay - which makes absolute sense!
Sorry to go off on a tangent with this one. I'm obviously having a bit of a duhhh day...
