Anyone in Uk joining the NCT?

Not sure if I should join? Want to join to meet other mums in same boat but also a bit scared to join as I'm not sure if I'd fit in. As area I live have some extremely rich people or people that have been to university or in very top jobs.  I work as a nanny! And never been to university. So just not sure how I would been seen. I think there would be a few down to earth people there. But worried If there wasn't.
