...there are two things you might find helpful.
The Sept ante natal thread here on MN: www.mumsnet.com/Talk/antenatal_clubs/2366372-September-crew-baby-bumps-are-appearing-and-were-emerging-as-team-blue-pink-or-yellow-Thread-8
And the Sept ante natal MN group on Facebook. It's absolutely secret so none of your friends will see you post on it. 85ish members so far (and 15 babies so far arrived!) If you'd like to join it PM me your email address and I'll send you an invite.
Good luck to all September mummies!
