9w 5d Swelling?

I had my first ultrasound today and I was told there was a lot of swelling around the baby’s head. Dr says they can’t tell anything until next ultrasound or genetic testing. What does this mean!??? Trying not to freak out but it just seemed weird how she kept talking about getting the genetic testing done. (And I don’t think it was for the money because she told me how to get it cheap)
