The 7-week ultrasound scan is a crucial milestone in pregnancy, providing expectant parents with a first glimpse of their developing baby. At this stage, the embryo has grown significantly, and its vital organs are functioning. This scan, also known as a dating scan or early pregnancy scan, serves multiple purposes, including confirming the pregnancy, determining the gestational age, and identifying any potential complications. In this article, we will guide you through what to expect during your 7-week normal ultrasound scan.
Preparation for the Scan
Before attending your 7-week ultrasound scan, it is essential to prepare yourself. You may be asked to arrive with a full bladder, as this will help improve the image quality. Wearing comfortable clothing and removing any jewelry or accessories that may interfere with the scan is also recommended. Additionally, you may want to consider bringing a support person, as they can provide emotional comfort and help you remember any important details discussed during the scan.
What Happens During the Scan
During the 7-week ultrasound scan, a trained sonographer will apply a transvaginal ultrasound probe to obtain clear images of the embryo. This probe is gently inserted into the vagina, and a small amount of gel is applied to facilitate the scanning process. The sonographer will then use the probe to capture images of the embryo, measuring its size and assessing its development. The entire process typically takes around 15-30 minutes, depending on the complexity of the scan and the number of images required.
| Gestational Age | Embryo Size | Developmental Milestones |
|---|---|---|
| 7 weeks | 10-15 mm | Heartbeat visible, limb buds present |
| 7.5 weeks | 15-20 mm | Embryo's major organs forming, digits visible |
