Worried for my baby girl

Jessica

So I’m worried 😔 my DD is suppose to be 11/19 and I just came to a private ultrasound scan for gender confirmation and my baby girl measured smaller . According to my DD I’d have to be 15w5d and My baby girl is measuring 14w4d 😢 she seemed healthy and good heart rate and very active . But I’m just worried she’s not growing how she’s suppose to 😢 she got a DD OF 11/27 . Has that happened to anyone ?
