Not til after the scan. Mostly the people I'm trying to hide it from are work colleagues and I really don't want to be announcing at the office before our scan as we won't be telling most friends and family til after then either. Somewhat fortunately, we don't live close to any family, so though we talk to them on the phone and skype we won't be physically seeing anyone in the next few months, so it won't be too hard to hide it from them. It will be a bit trickier with friends and also work once it gets a bit more obvious though. I was in maternity trousers and leggings from 7/8 weeks last time so I suspect I will be again and then it won't be as easy. I have one friend whose already asked a few times if I'm pregnant so I think she has her suspicions! It doesn't quite feel as real this time, not sure why, maybe just too busy with other things, so will be nice after the scan to be able to take it all in and then will show things off a bit more.
