Yes, it is possible to have an anomaly scan at 17 weeks and 2 days of pregnancy. Anomaly scans, also known as mid-pregnancy ultrasound scans, are typically performed between 18 and 21 weeks of gestation. These scans are used to assess the baby's growth and development, as well as detect any potential abnormalities or birth defects. While the ideal time for an anomaly scan is around 20 weeks, having it done a few days earlier should not significantly affect the accuracy or reliability of the results. It is important to consult with your healthcare provider or obstetrician to schedule the scan and ensure that you meet all necessary requirements for the procedure. They will be able to provide you with more specific information based on your individual circumstances.
