it's great that we have all this technology that can alert us to problems early.
the downside is that we now have to contend with all the 'maybes' that these tests raise.
i know it's not really possible to control one's fears 100%, but it's important for you to rein yourself in as much as possible. IF there's a problem you'll deal with it as well as your nature dictates and your doctors suggest. but there's probably not. and by letting yourself stay in a state of high anxiety, you're negatively affecting your baby anyway.
use whatever techniques typically help you to compose yourself, and wait for further information..
