I would go for it, naturegirl! I had just gotten my + preg test a week before when I hopped on a flight for my Christmas vacation. All turned out very well with my son, who is a healthy 2 year old now. I was much more worried about all the ultrasounds (supposedly for my baby's own good) during my pregnancy than about the little radiation from the flight. The one concern I would have about traveling while newly pregnant: if you experience "morning" sickness during your pregnancy, you might feel as miserable while traveling as I did, and that part was no fun at all. Good luck to you!!
