This is called an anembryonic pregnancy, which is also known as a blighted ovum. Or it may be that your baby started to grow, but then stopped growing and they have no heartbeat. Occasionally it happens beyond the first few weeks, perhaps at eight weeks or 10 weeks, or even further on.
Is it possible to not see a heartbeat at 9 weeks?
If you are at least eight or nine weeks along at your first prenatal visit, your doctor or midwife may use a fetal Doppler (or a fetal Doppler stethoscope) to pick up the sound of your babys heart beating. Sometimes, the sound of a fetal heartbeat is not detected at this time.
What causes a fetus heart to stop?
The most common cause is a problem in the placenta (the tissue that carries food and blood to the baby). Birth defects and genetic disorders can cause IUGR. If the mother has an infection, high blood pressure, is smoking, or drinking too much alcohol or abusing drugs, her baby might have IUGR.
