You might not be able to hear a baby’s heartbeat at your first ultrasound. Most commonly, this is because it’s too early in the pregnancy. This doesn’t necessarily mean there’s a problem. The doctor may discover on ultrasound that the fetus is smaller than it should be and does not have a heartbeat or the mother may begin to have bright red bleeding and cramping.
If there is no visible heartbeat, a miscarriage is about to occur. Ultrasound measurements indicate that a heartbeat should have been present. Your doctor may also measure the crown to rump measurements with the foetal pole as a basis to determine the risk of a miscarriage.
If an embryo is larger than 5 millimetres and has no heartbeat, it may indicate a miscarriage. The transvaginal ultrasound is generally used because an abdominal ultrasound is much less accurate this early in pregnancy. The gestational sac is usually seen on ultrasound by 5 weeks gestational age but is sometimes seen as early as 3 weeks gestational age. The guideline is that if the gestational sac measures >16-18mm with no fetal pole or the fetal pole measures 5mm with no heartbeat (by vaginal ultrasound), then a diagnosis of miscarriage or blighted ovum is made. If the fetal pole is too small to take an accurate measurement, then a repeat scan should be done in 3-5 days.
crown-rump length (CRL) of ≥ 7 mm and no heartbeat on a transvaginal scan mean sac diameter (MSD) of ≥ 25 mm and no embryo on a transvaginal scan absence of embryo with heartbeat ≥2 weeks after a scan that showed a gestational sac without a yolk sac. The gestational sac, the yolk sac and the fetal pole were all visible but they did not see a heart beat. They said I could either be too early or that something happened (I was pregnant in December 2014 but had a natural miscarriage at 6 weeks) but were more focused on the missed miscarriage theory. The first 3 weeks after they told me the baby was dead i had no signs of a miscarriage, no cramping, no bleeding.
Then I had another ultrasound about a week ago and confirmed still no heartbeat at 11 weeks and still no signs of miscarriage except that the baby was still the size of an 8 week old fetus (it had not grown over the past 3 weeks). About 6 weeks or so in pregnancy, the heartbeat of the fetus may be detected via an ultrasound, which, however, might vary a lot in actual situations. Doctors usually won’t advise an ultrasound at 6 weeks, because it usually can show nothing or very little image of the fetus, even for a perfectly normal pregnancy. Pregnancy loss can occur during any stage of pregnancy, though it’s most common in the first trimester. If we do an ultrasound and the length of the baby is more than 7mm, we should always see movement of the fetal heart.
If we don’t, we know the pregnancy is not going to develop.
