Six weeks of pregnancy without fetal heartbeat

During pregnancy, prenatal examinations will be carried out several times to confirm the safety of the baby and the mother. Several prenatal checkups may address some minor problems in a timely manner, making it easier to deal with them as soon as possible. As the fetus grows, electrocardiogram (ECG) signals such as fetal heartbeat will gradually appear, which also indicates that the child is growing and developing healthily. Below I will introduce to you the reasons why there is no fetal heartbeat or fetal bud in the sixth week of pregnancy. You can all take a look.

Reasons for no fetal heartbeat or fetal bud at six weeks of pregnancy:

1. Genetic defects: such as abnormalities in sperm or egg chromosomes, chromosomal abnormalities in either spouse; reasons on the maternal side, such as the mother suffering from some diseases, or endocrine abnormalities, bad habits such as smoking and drinking, traumatic stimulation, and some mental factors.

2. Pregnant mother factors: such as poor physical condition or illness, incomplete cervical closure, corpus luteum insufficiency, endometriosis, immune factors and immune dysfunction, and abnormal growth and development of the test tube embryo itself.

3. Environmental factors: such as compounds, high temperature, microwave heating, noise, radiation and other physical factors.

4. The pregnant woman's own extracellular fluid: The pregnant woman herself also affects the changes in the fetal heartbeat. For example, if the pregnant woman has a fever, the fetal heartbeat will often exceed 160 beats/minute. The pregnant woman has a relatively hyperactive thyroid hormone, her own heartbeat is fast, and the fetal heartbeat also often exceeds 160 beats/minute. Sometimes the pregnant woman takes some medicines, which act on the fetus through the placenta, causing the fetal heart rate to slow down. When the fetal heart rate continues to be slow, it is important to check whether the fetus has congenital heart disease.

What should I do if I have no fetal heartbeat during pregnancy?

Generally speaking, if no fetus is found after the first prenatal check-up, the doctor will suggest that the pregnant woman have another check-up in another week. Pregnant women can also go to other prenatal doctors to check fetal heartbeats on their own. If there is no fetal heartbeat after several examinations, you need to be hospitalized immediately for further examination and receive corresponding treatment.

Generally speaking, the disappearance of fetal heartbeat means the death of the fetus. If color ultrasound examination finds that the fetal heartbeat and fetal movement have disappeared, it can be diagnosed as fetal stillbirth. Once the fetus is diagnosed with perinatal death, a uterine curettage should be performed immediately to prevent it from staying in the uterine cavity for too long and causing blood clotting problems in the pregnant mother.

If the fetus is retained in the uterus for a long time, it may cause coagulation disorders in the pregnant mother, resulting in focal intravascular coagulation and severe bleeding. If the immune systems of the mother and child are not compatible, the pregnant mother may resist the test tube embryo and cause miscarriage.
