Is It Normal for a Fetus Not to Have a Heartbeat at 8-9 Weeks? - Obstetrics and Gynecology

Is the fetus normal in the early stages of pregnancy?


Hello Doctor: I have several questions to ask you! I found out I was pregnant on October 27, which means I should be about 8 to 9 weeks along.
However, my obstetrician informed me that the fetus has no heartbeat.
Is this normal? My friends told me that they only detected a heartbeat between 11 to 13 weeks.
I have no discomfort or bleeding.
If the fetus is a blighted ovum, should I handle it promptly? My doctor mentioned that it’s not necessary to remove it surgically and that I could let it pass naturally over 4 to 8 weeks.
Would this harm my body? I am confused about whether to listen to my friends and wait or to proceed with removal.
Could you please provide me with some guidance?

MAY, 30~39 year old female. Ask Date: 2006/12/11

Dr. Li Guanghan reply Obstetrics and Gynecology


Hello: For women with a regular menstrual cycle, an ultrasound at seven weeks of pregnancy should be able to detect the fetal heartbeat.
If the heartbeat is still not visible at nine weeks, the likelihood of a blighted ovum is high.

It is understandably concerning to hear that a fetus does not have a detectable heartbeat at 8 to 9 weeks of gestation. Typically, a fetal heartbeat can be detected via transvaginal ultrasound around 6 to 7 weeks, and by 8 weeks, it is expected to be present. However, there are several factors to consider in your situation.

First, it is important to confirm the gestational age accurately. If there is any uncertainty regarding the timing of conception, it may be possible that the fetus is not as developed as initially thought. This could explain the absence of a heartbeat. In some cases, the position of the ultrasound probe or the quality of the ultrasound equipment can also affect the ability to detect a heartbeat.

If your healthcare provider has confirmed that there is no heartbeat, it may indicate a missed miscarriage, also known as a silent miscarriage, where the fetus has stopped developing but has not yet been expelled from the body. In such cases, the body may take time to recognize the loss, and it can take weeks for the pregnancy tissue to be expelled naturally.

Regarding your question about whether to wait or proceed with a medical intervention, it is essential to weigh the risks and benefits. Allowing the body to naturally expel the tissue can be a less invasive option, but it may take time—typically 2 to 4 weeks, and sometimes longer. If you choose to wait, it is crucial to monitor for any signs of complications, such as heavy bleeding or severe pain, which would necessitate immediate medical attention.

If you are considering a medical or surgical intervention, such as a dilation and curettage (D&C), it is generally safe to do so. However, the timing of the procedure can depend on various factors, including your health, the presence of any symptoms, and your personal preferences. Your healthcare provider can guide you on the best course of action based on your specific circumstances.

It is also worth noting that while some friends may have experienced a later detection of a heartbeat, this is not the norm. Each pregnancy is unique, and individual experiences can vary widely. It is essential to rely on medical advice rather than anecdotal experiences when making decisions about your health.

In conclusion, if you are feeling uncertain, it may be beneficial to seek a second opinion from another healthcare provider. They can perform additional ultrasounds or tests to confirm the status of the pregnancy and help you make an informed decision about how to proceed. Remember, your emotional and physical well-being is paramount, and it is essential to choose a path that feels right for you.
