Scared!!!!

When I was 20 weeks pregnant, I did my anatomy ultrasound which showed baby had cyst in brain, now I am 26 weeks, but I have to get a repeat anatomy ultrasound to see if the cyst is still there, have to wait till 32 weeks. Been reading about cyst in brain, we also did chromosome testing(also called genetic testing) that came out perfectly normal. Reading all these negative stuff about baby having cyst, it’s scary ,
