NOT announcing

I'm barely pregnant (4w3d) with #2 and we are waiting to announce until I'm 8 or 9 weeks along. However, I have told people that we were trying. One of these people asked me last night straight out "So, any news about a baby?" And being the horrible liar that I am I just got a deer in the headlights look on my face while trying to figure out what to say. Of course she immediately knew the answer was yes and I was left sputtering "Crap crap crap don't tell ANYONE!!" So if you're waiting/have waited to announce the pregnancy to the general public, how did you deal with outright questions about pregnancy? Again, I'm a really bad liar and wear my feelings on my sleeve so simply lying about it is out for me.
