When Will I Have My Early Pregnancy Scan?

Your doctor will first have a discussion with you to understand your medical history and any family histories of pregnancy related complications.

This will most likely happen between week 6 and week 10 of your pregnancy .

When Will I Have The Next Of My Early Ultrasound Scan?

Unless your doctor thinks otherwise, you will not be required to do an early ultrasound scan.

The first pregnancy ultrasound scan will be around the time you are 12 weeks pregnant. This ultrasound test is also sometimes known as the ‘dating’ scan. This is because it helps your doctor to place an estimate about the date of delivery. This will be your Estimated Delivery Date or EDD .

The second ultrasound scan will be around the time you are between week 18 and week 21 of your pregnancy . This ultrasound test is also sometimes known as the ‘anomaly’ scan. This is because it will help your doctor to check for any structural abnormalities, known as anomalies, in your baby.

What Can I Expect During The EDD Scan?

While you are getting your dating scan done, the sonographer will ask you to lie down on your back and apply some gel on your tummy. Your doctor will hold a device known as transducer in the hand and move this on your tummy. This will help your doctor get an image of your baby. This particular ultrasound scan will help your doctor to measure the length of your baby’s crown ramp. The crown ramp length means your baby’s length from head to the bottom.

How Do These Early Scans Help My Unborn Baby?

Ultrasound scans are an extremely important part of pre natal care. The early ultrasound scans will help your doctor confirm a uterine pregnancy and also monitor fetal heartbeat.

The other ways in which an ultrasound scan will help are:

  • Checking your baby’s size
  • Confirming your current week of pregnancy.
  • Check for multiple pregnancies

Your doctor will need to refer you for an ultrasound scan while you are pregnant. You will be required to show an authorized letter before you get an ultrasound scan done. This is to ensure that you have your doctor’s permission for the first ultrasound scan during pregnancy.

Speak to your doctor about any concerns you may have regarding the early pregnancy scans. Rest assured, it will not harm your baby or you.
