Genetics testing

I was told the baby has a lot of fluid on the back of its neck at week 9. My doctor said it could be nothing but I went a head and told her I’d like to do the genetics test. So I’m going in on the 14th of dec. I am so worried! I should be 10 weeks 6days as of today with 2 weeks to go before the test. I don’t have any serious health issues and neither does my husband. So I don’t think our baby will have any issues but I’m just so anxious and scared. Has anyone else’s week 9 ultrasound looked like mine?
