First pregnancy ultrasound: when to have it and why
By Dr Oussama Rachid ·
The first ultrasound confirms the pregnancy, dates it and checks that it is developing in the right place. It is most often done in the first trimester, by the endovaginal or abdominal route depending on the stage and the situation. This article explains what it offers and how to prepare. It is informational: your schedule is set with your doctor.
What it shows
That the pregnancy is in the uterus, the number of embryos, the heartbeat from a certain stage, and an estimate of the due date.
Endovaginal or abdominal?
Very early in pregnancy the endovaginal route gives sharper images. Later, the abdominal route is often enough. The choice is made with you: see the Endovaginal ultrasound page.
How to prepare
Bring your documents and note the date of your last period. For an endovaginal scan it is usually better to empty your bladder; for an abdominal scan the doctor tells you whether the bladder should be full.
Bleeding or pain
Do not wait for your appointment: call the clinic or the emergency number. If you cannot wait, go to the nearest emergency department.
