Early Pregnancy Ultrasound
An early pregnancy scan uses ultrasound to assess a pregnancy during the first trimester. It can help confirm its location, check for a heartbeat, estimate how many weeks pregnant you are and identify twins or more. It may also investigate pain or bleeding, although a repeat scan may be needed if it is too early to give clear answers.
When the Service May Be Recommended
An early pregnancy consultation and scan may be recommended if you experience:
Vaginal bleeding
Pelvic or abdominal pain
Severe nausea or unusual symptoms
Concerns about miscarriage
Prompt assessment helps ensure appropriate care and reassurance.
What to Expect
The procedure
Early pregnancy scans are usually performed using a transvaginal ultrasound, which provides the clearest images in early pregnancy.
You will lie comfortably on an examination couch.
A small ultrasound probe is gently inserted into the vagina.
The scan produces detailed images of the uterus and developing pregnancy.
The findings are explained to you during the appointment.
The scan itself typically takes 10–15 minutes.
Most patients find the procedure comfortable and similar to a routine gynaecological examination.
What can an early pregnancy ultrasound show?
An early scan can provide several important pieces of information.
Confirmation of the pregnancy location - the scan confirms that the pregnancy is within the uterus, helping to exclude ectopic pregnancy, where the pregnancy develops outside the womb.
Detection of a fetal heartbeat - by around 6–7 weeks, the scan can usually identify a fetal heartbeat, which is a reassuring sign of early pregnancy development.
Date of the pregnancy - measurements taken during the scan help determine the gestational age and estimate the due date.
Identification of multiple pregnancies - the ultrasound can detect twins or multiple pregnancies at an early stage.
Frequently Asked Questions
Is early pregnancy ultrasound safe?
Yes. Ultrasound uses sound waves rather than radiation and is considered safe for both mother and baby.
When can a heartbeat be seen?
A fetal heartbeat is usually visible from around 6 weeks of pregnancy.
What if the heartbeat cannot be seen?
If the pregnancy is very early, it may be too soon to detect a heartbeat. In this situation, a repeat scan after 1–2 weeks may be recommended.
Do I need a full bladder?
For early pregnancy scans performed transvaginally, a full bladder is usually not required.
Early pregnancy can bring both excitement and uncertainty. A specialist ultrasound scan provides reassurance and accurate information about your pregnancy.
