Anatomy scan soft markers!

Hello ladies, in my 19th week anatomy scan ultrasound, two soft markers were found.They were choroid plexus cyst and echogenic intracardiac focus in left ventricle. I just can’t shake my anxiety at this point even though Dr said these doesn’t affect development and most go away by 24 weeks. However, it can also be a marker for a chromosome abnormality. I consulted a fetal medicine, went ahead and did a NIPT test and awaiting results now. My double marker test around 12 weeks came negative and everything else looked normal in the 19th week scan besides these.Has anyone ever had this happen? Help calm this momma down.
