I have just received a letter this morning that says

Appointment for ultrasound - us foetal growth, us obs dopp umbilical art B

I'm really confused by this with my other 2 pregnancies I had the standard 2 scans at 12 and 20 weeks (I'm UK) she said everything was fine at my 20 week scan im 28weeks now and panicking because now I think there is something wrong and I can't get through to any clinic by phone 😢 does anyone know what this is for to settle my nerves until I can get someone to answer the phone to me?
