What does it mean when there is no fetal pole?

An absent fetal pole can mean several things, including: Blighted ovum: A blighted ovum (anembryonic pregnancy) is when a fertilized egg implants in the uterus but doesn’t grow into an embryo. This causes an early miscarriage. Too early: If a pregnancy isn’t far enough along, you may not be able to see the embryo yet.

When should you see a fetal pole on ultrasound?

The fetal pole is usually identified at ~6.5 weeks with transabdominal ultrasound imaging and at ~6 weeks 2 with transvaginal ultrasound imaging, although it may not be seen until ~9 weeks in some cases.

Can ultrasound detect baby at 7 weeks?

Ultrasound can usually detect a fetal heartbeat at 6-7 weeks of pregnancy, when the baby’s length or crown-rump length (CRL) is 7mm. If the CRL is less than 7mm and no heartbeat is seen, this may be because the embryo is too young. You will be offered a re-scan.

Is no fetal pole at 7 weeks normal?

If there are no signs of pregnancy or inconsistent signs, like a large gestational sac without any yolk sac or fetal pole, it may mean you have a blighted ovum or are otherwise miscarrying. This is very common in the earliest weeks of pregnancy, when the risk is the highest.

How long does it take for the fetal pole to develop?

The fetal pole becomes visible somewhere between 5 1/2 and 6 1/2 weeks of gestational age (typically determined based on the date of the last normal menstrual period). Any small error in dating the pregnancy can throw off an ultrasound interpretation.

How long does it take for fetal pole to develop?

The fetal pole becomes visible somewhere between 5 1/2 and 6 1/2 weeks of gestational age (typically determined based on the date of the last normal menstrual period).

What happens if no fetal pole is detected at 7 weeks?

If no fetal pole is detected at 7 weeks of pregnancy, your doctor will order a second ultrasound in three to seven days to make sure the baby is still alive and developing. If no fetal pole is seen, your doctor will give you another ultrasound.

What is the point of a 7 week ultrasound?

Aside from detecting a heartbeat, the point of a 7-week ultrasound is to take measurements of these fetal developments so your doctor has a better idea of where you are in your pregnancy. That’s why this is often called a dating ultrasound: The measurements are a good indicator of gestational age.

How many gestational sacs should be visible at 7 weeks?

If you’re estimating your pregnancy accurately, multiple sacs should be pretty visible on a transvaginal ultrasound at 7 weeks. If your twins are identical — meaning, one egg was fertilized but then split in two — there’ll only be one gestational sac; however, more than one yolk sac, fetal pole, and heartbeat may be visible.

What to do if there is no fetal heart at 7 weeks?

Many couples who have no fetal pole at 7 weeks of pregnancy have a child after the birth. But if there is no fetal heart at seven weeks, it is important to consult your doctor immediately. Your doctor may be able to give you an ultrasound at 7 weeks if the baby is still growing.
