Help, I'm freaking out :(

I'm 20 weeks pregnant, I had my anatomy scan the other day and my doctor just emailed me the results. She said everything looked perfectly fine.... but my babys ultrasound on her brain showed that she has choroid plexus cysts. And that most of the time they resolve on there own, but that she wanted to see me for a follow up to look at the chambers of her heart and hands. She said not to freak out, and since I had the NIPT test that showed no chance of a genetic abnormality not to worry. But I'm a first time mama, and I'm worrying. Does anyone have some insight on this? 😭
