Breast Tomosynthesis: How to Prepare and What to Expect
January 5, 2025
Read MorePatients with healthy pregnancies generally have at least two ultrasound scans, one during the first trimester and one during the second trimester. Though the first ultrasound scan usually happens between weeks 10 and 13, it is not uncommon for the first pregnancy ultrasound to happen at 9 weeks.
This article will examine why you might have an ultrasound at 9 weeks, what to expect during your early pregnancy scan, how to prepare for your appointment, and how to access your results.
The first pregnancy ultrasound usually takes place somewhere between weeks 10-13. Sometimes called the dating scan, this first ultrasound helps your healthcare team determine the gestational age of the fetus. Occasionally the first ultrasound might happen even a little earlier, depending on your personal health circumstances or the practices of your primary healthcare provider.
Here are several reasons you might have an ultrasound at 9 weeks:
This ultrasound might be the first opportunity to visually confirm your pregnancy. At 9 weeks, the fetus will be approximately 2.5 cm long (1 inch), about the size of a large grape, and will weigh about 2 grams.
At 9 weeks, an ultrasound can check that your pregnancy is properly implanted in your uterus (e.g. intrauterine). An ectopic pregnancy is extrauterine, meaning it is implanted anywhere outside your uterus, for instance, in the fallopian tubes. Ectopic pregnancies are not viable.
If you have twins or triplets in your family history, you may have a higher-than-average chance of multiple pregnancies. This early pregnancy scan should reveal if you have multiple viable embryos.
At 9 weeks, the sonographer can often measure the fetus’ crown-rump length, which helps establish gestational age.
The weeks of your pregnancy are measured from the first day of your last menstrual period. If you’re unsure when that was, the fetal crown-rump length can help establish or adjust an estimated due date.
Although some spotting is well within the confines of normal, you might have an ultrasound at 9 weeks if you experience vaginal bleeding.
If your family health history or ongoing health issues mean your pregnancy is considered high risk, you might have an ultrasound scan at 9 weeks.
High-risk factors can include:
During your ultrasound scan, the sonographer uses a transducer which emits high-frequency sound waves. Those sound waves bounce off your internal tissues and structures, and the ‘echoes’ are collected by the ultrasound machine and compiled into live and still images.
At 9 weeks pregnant, an ultrasound might be internal (transvaginal) or external (transabdominal), depending on each specific pregnancy. In early pregnancy (e.g. before 10 weeks), fetal structures are very small, and it is easier to get visibility with an internal ultrasound.
In a transabdominal ultrasound, the transducer is moved across the abdominal skin through a layer of sound-conducting gel. During a transvaginal ultrasound, the gel-coated transducer is inserted into the vaginal canal to capture better images.
The 9-week fetus is still very small, only about an inch long. The ultrasound will likely show some of the associated prenatal structures, such as the umbilical cord and the gestational sac, a black shape like a circle around the embryo filled with amniotic fluid.
You might also see the yolk sac in the ultrasound image, which provides the embryo with nutrients and is itself absorbed by the end of the first trimesters.
It is too early for fine detail, but you are likely to see the larger shape of the head as distinct from the body, and you may be able to see the shapes of developing limbs.
You may be able to hear a heartbeat during a 9-week scan, but it is also possible and normal not to hear it. It depends on which method of ultrasound you have, transabdominal or transvaginal. The fetal cardiac structure is still very tiny at this stage, and the heartbeat might not be apparent during a transabdominal ultrasound.
It also depends on what type of ultrasound you have. A Doppler ultrasound is a specialized type of ultrasound that visualizes blood flow. Doppler ultrasounds are usually the first to be able to distinguish fetal heartbeats and are typically more reliable for detecting heartbeats than standard transabdominal imaging.
Ultrasounds are safe, non-invasive imaging scans. They don’t often involve too much preparation but be sure to check with the imaging clinic for any special instructions.
There are a few things you can do to be well-prepared for your ultrasound scan, including:
Depending on the method and type of ultrasound you have, your scan should take between 30-60 minutes. Afterwards, you can go about your day as usual.
At 9 weeks pregnant, you’re in the last month of your first trimester. Pregnancy hormones can have unexpected effects both physically and emotionally. Each pregnancy is a singular experience, but many pregnant women have reported feeling at least some of the following pregnancy symptoms and signs:
The radiologist will release the images and a report to your referring physician, who will discuss the results with you at a follow-up appointment. But you might not want to wait a few days for the process to take place: it can be very exciting to see ultrasound pictures of your early pregnancy.
