Disappointing anatomy scan

I’m 19 weeks today and I had my anatomy scan this evening. First the baby is measuring a week behind which I’m not too happy about since she was on mark with my last two scans. Then bc she’s so stubborn and wouldn’t move I have to get another scan so they can get better pics of her heart 😒. Hoping her measurements don’t mean something is wrong. I’m happy I’ll get to see her again but anatomy scans are stressful bc they don’t tell you anything. Anyone else get told their baby was behind this far along?
