The clinician looks for signs that the pregnancy is inside the uterus.

Early-pregnancy ultrasound:
clear information at the right time
An early scan can help assess the location and stage of a pregnancy, but timing matters. If the pregnancy is very early, a repeat scan or additional assessment may be needed before a definite answer is possible.

What can an early scan assess?
Gestational age
Measurements can help estimate how far the pregnancy has progressed.
Development
A fetal pole and heartbeat may be visible when the pregnancy is far enough along.
Pain or bleeding
A scan can form part of the assessment when symptoms need investigation.
A scan may also identify more than one pregnancy or other findings that need follow-up. It is one part of the assessment and must be interpreted alongside your dates, symptoms and examination.
Why a scan can be uncertain very early
It is not always possible to confirm location, viability or exact dates from a single very early scan. This does not automatically mean that something is wrong. The clinician may recommend a repeat scan, blood tests or referral, depending on your symptoms and findings.
Do not rely on an inconclusive early scan for reassurance if symptoms are worsening. A pregnancy outside the uterus can be dangerous and may not be visible at first.
Transabdominal and transvaginal scans
Transabdominal
The probe moves over the lower abdomen. A full bladder may be requested. Very early detail can be limited.
Transvaginal
A slender covered probe is inserted into the vagina with your consent. It usually gives a clearer view in early pregnancy.
The clinician should explain the recommended scan, answer your questions and obtain your consent. If a transvaginal scan is unacceptable to you, say so; the limitations of other approaches should then be explained.
DO NOT WAIT FOR A ROUTINE APPOINTMENT
Seek urgent medical care for:
- Severe or one-sided abdominal or pelvic pain.
- Shoulder-tip pain, fainting, collapse or marked dizziness.
- Heavy bleeding or rapidly worsening symptoms.
These can be warning signs of serious bleeding or ectopic pregnancy. Go to the nearest emergency department or contact emergency services if symptoms are severe.
Preparing for your appointment
- Bring the date of the first day of your last menstrual period if known.
- Tell the clinician about pain, bleeding, previous ectopic pregnancy, fertility treatment and relevant medicines.
- Bring previous scan reports or blood-test results if you have them.
- Ask the clinic whether you should arrive with a full bladder.
An ultrasound is included in the R500 confidential pregnancy-options consultation at Benoni Healthcare. For other scan appointments, contact the clinic to confirm the service, preparation and fee.
