Your first scan

Your first pregnancy scan, often the "dating scan," is usually around 11-14 weeks to confirm pregnancy, determine your due date, check development, and screen for conditions like Down's syndrome.

Early scans (6-9 weeks) may be offered for reassurance or medical reasons, checking viability, heartbeat, and number of babies, using ultrasound to measure growth and assess the uterus.

Preparation often involves a full bladder for clearer images, and these scans are vital for confirming the pregnancy is progressing normally.

What to Expect
Timing: Typically 11-14 weeks (the 12-week scan), but can be earlier (6-9 weeks) for viability or private scans.

Purpose: Confirm pregnancy, date it accurately (due date), check baby's health/growth, look for multiple babies, and screen for chromosomal conditions (like Down's via nuchal translucency).

Procedure: A sonographer uses an ultrasound machine to create images; you may need a full bladder for a clearer picture.

Results: Often given at the time of the scan.

Why Early Scans (Before 10 Weeks)
Viability: To detect a heartbeat and confirm the pregnancy is in the uterus.

Concerns: For bleeding, pain, previous pregnancy issues, or if using assisted conception.

Information: Provides reassurance and establishes gestational age early on.

Preparation
Full Bladder: Drink about a pint (0.5 liters) of water an hour before for clearer images in early scans.

Nervousness: It's normal to feel anxious; the scan provides important information, but it's a routine, safe procedure.
