20 week anatomy scan distressed momma : (

I went for my 20 week anatomy scan yesterday hoping all would be great. They ended up finding an “isolated liver calcification” or a bright spot on its liver. There were no other concerns. Two genetic tests at ten and twelve were negative for trisomies and the NT was negative as well. I am beside myself with worry-this is our second pregnancy, rainbow baby. Any information or experience would be appreciated very much!
