Congratulations and welcome!
I know what you mean about not telling anyone! We've decided to wait until at least we hear the heart beat to tell, because I've miscarried twice. It's too hard, months later for people to look at you weird, cause they knew you were pregnant and now you don't look like it. We are both so excited to tell though, we are jumping out of our skin. I have an US on Monday so we are hoping we hear the heartbeat then so we can tell people!
