Shadow

I'm so nervous. I got a call today about my anatomy scan I had at 20 weeks. At the appointment they said everything looked great. Now they're saying there is a shadow on my little girls heart. She was so active they couldn't get any pictures of facial structure to be able to rule anything out. I go in tomorrow to get my blood drawn for the genetics test (previously denied). I have another ultrasound in 2 weeks to see if they can get the face and if anything changed as far as the shadow. I'm so scared that something is wrong with my little girl. 😩
