Bilateral Coronoid plexus cysts

Hello everyone! I never post, but I am concerned. I’m currently living overseas and I’m in my 18th week of pregnancy.

I had my last ultrasound a couple days ago. And my Dr told me that the baby has bilateral coronoid plexus cysts, she got me very worried, because first she told me to take multiple viral test since she thought I had cytomegalovirus, then thanks God the test came back great. I called her and she said it might be linked to trisonomy 18, but all my genetic tests were fine and the rest of the baby ultrasound it’s ok. Now she wants me to do a few blood tests because she thinks it might be a hemorrhage in the baby’s brain. Is it me or she is just giving me all the worst scenarios? I’m going on Thursday again to take a neurosonography to check more detailed the baby’s brain. I had heard before that these cysts usually go away by themselves. I just can’t stop thinking that the Dr wants to find something that I hope it not there. I pray my baby is ok. I haven’t been able to sleep all these days
