When to book
Most women have this scan between 6 and 10 weeks, counted from the first day of the last period. Before about 6 weeks the pregnancy may be too small to see a heartbeat, which can mean an inconclusive result and a repeat visit.
Your doctor may advise an earlier scan if you have pain, bleeding, a previous ectopic pregnancy or miscarriage, or conceived through fertility treatment.
What the scan confirms
- Location: that the pregnancy is inside the uterus and not ectopic
- Viability: whether a heartbeat is seen for the stage of pregnancy
- Number of babies: and, for twins, whether they share a placenta. This matters for how the pregnancy is monitored
- Dating: crown-rump length (CRL) is measured to give the most accurate due date
- Other findings: such as fibroids or ovarian cysts that your doctor should know about
Abdominal or transvaginal?
Early in pregnancy, a transvaginal (internal) scan usually gives clearer pictures, because the probe sits closer to the uterus. It is safe for the pregnancy and takes a few minutes. An abdominal scan may be enough later in the first trimester.
The scan method is always explained first and done only with your consent. You are welcome to have a female companion in the room.
How to prepare
- For an abdominal scan, you may be asked to come with a comfortably full bladder
- For a transvaginal scan, you will be asked to empty your bladder first
- Bring your pregnancy test result, the date of your last period, and your doctor’s note
- Form F under the PCPNDT Act is completed for every pregnancy scan, so carry a photo ID
If the result is not clear yet
Sometimes the pregnancy is too early to confirm a heartbeat, or the dates are uncertain. This is common and does not by itself mean something is wrong. A repeat scan 7 to 14 days later usually gives a clear answer. Dr. Nayana explains what was seen and when to return before you leave.
