Extra Fluid at 10 week scan..

I had my first transvaginal ultrasound today! 10 weeks 3 days... Everything was on point but my ob noticed extra fluid around the neck and spine... She said sometimes this resolves on its own but sometimes this indicates another problem like heart defects and/or chromosome abnormalities... This made me very scared. I go in again in 2 weeks for another scan to see if it has resolved and if not, we will look at options then. Has anyone been in the same position or something similar? Outcomes? Thanks for reading and replying. ❤️❤️
