Ultrasound is an effective imaging technique that uses sound waves to create images of your internal structures during pregnancy. Unlike X-rays, which use radiation that can be harmful during pregnancy, ultrasounds are considered low-risk and are widely used to monitor pregnancy.
Research has found no connection between ultrasound use during pregnancy and physical complications in babies after birth. However, the main risk associated with ultrasound is the rare possibility of misdiagnosis—where something concerning may appear on the scan but turns out to be harmless later.
Despite this minimal risk, ultrasounds remain an essential tool for observing key details about your pregnancy.
Why Do I Need an Ultrasound?
An ultrasound can provide 3 critical pieces of information early in pregnancy, including:
1. Gestational Age
Even if you track your cycle or have regular periods, determining how far along your pregnancy is without an ultrasound can be difficult. Measurements taken during an ultrasound help accurately estimate gestational age, which is essential for understanding your options and next steps.
For example, a medication abortion is only FDA-approved if your pregnancy is under 10 weeks gestation.
2. Location
Most pregnancies develop in the uterus. However, in rare cases, a pregnancy can develop outside the uterus, called an ectopic pregnancy. This condition is life-threatening and requires immediate medical care. Ultrasound helps confirm the pregnancy’s location and identify potential risks.
3. Viability
It’s possible to have a positive pregnancy test even after a miscarriage. An ultrasound checks for signs of life, like a heartbeat, to confirm whether the pregnancy is viable. If not, medical follow-up may be necessary.
How Many Ultrasound Scans Will I Need?
While ultrasounds are vital diagnostic tools, the goal is to use the fewest scans necessary. Typically:
- The first ultrasound establishes gestational age, location, and viability.
- Additional ultrasounds may occur to monitor your pregnancy’s development.
Your doctor will recommend the number of scans based on your unique situation. For example, high-risk pregnancies often require more frequent monitoring.
