Congratulations on your pregnancy
I posted a reply about this to someone else earlier today.
*snip*
We told our parents as soon as we found out, and a couple of close friends and my boss (I'm a nanny and she needed to know). Everyone else we waited till 12 weeks.
A good friend said to me her measure had been, would she be able to tell these people in person should she miscarry in those early weeks. It came down to close family and friends yes, others no. I thought about it and felt the same. I didn't want to tell *everyone* just in case something went wrong and I then had to explain. It'd have been hard enough just telling those I love, let alone work colleagues and friends. I found it a good yardstick to measure whom to tell.

End of the day, do what you feel comfortable with. If thats only telling a few close and trusted family and friends then
If once past 12-13 weeks and wanting to gradually share your news with others, then you can pick and choose.
I have to admit I've still not really told all that many people. Lots of my friends and general aquaintances have no clue. I doubt I'll say anything until I start showing now. But that's just me
