Ultrasound results

Kiersten

I’m 27 weeks and I had the normal anatomy scan when I was 20 weeks. They didn’t tell me anything was wrongg with baby. They called me a couple days later saying I had to come in in 6 weeks to do another ultrasound just bc of my BMI. Well I just got a call from the office saying I needed to come in tmw so the doc can go over the ultrasound with me! I’m panicking. Does anyone know why they would need me to come in to go over the results. Is there something wrong?
