Will I have miscarriage if there is no fetal heartbeat during pregnancy?

Some pregnant women did a prenatal check-up and found that there was no fetal heartbeat. This is a strange thing and should have a lot to do with the physical condition of the pregnant woman herself. If the fetus has no heartbeat in early pregnancy, abortion can be performed directly to expel the fetus from the body. It affects women's own health, but it happens in the second trimester, so many things need to be paid attention to. So will a miscarriage occur if there is no fetal heartbeat during pregnancy?

Will there be miscarriage if there is no fetal heartbeat?

In the second and third trimesters, usually between 17 and 20 weeks, the doctor can hear the fetal heartbeat in the abdomen using an ordinary stethoscope. The normal fetal heart rate is between 120-160 beats per minute. Sometimes there will be a brief pause, or the speed may reach 180 beats per minute, which is a normal phenomenon. However, if this phenomenon occurs frequently or for a long time, you should seek medical attention in time.

Too high or too low may be related to fetal hypoxia. If the fetal heartbeat disappears, it may be related to fetal malformation, severe anemia, pregnancy-induced hypertension, etc. If it is confirmed after verification that the fetal heart rate has stopped, uterine curettage should be performed promptly.

Fetal Dopplers are not used before 15 weeks of pregnancy. Pregnant women between 15 and 28 weeks of pregnancy need to have a prenatal check-up every 4 weeks. Pregnant women between 28 and 36 weeks of pregnancy need to have a prenatal check-up every two weeks.

Therefore, doctors generally do not use Doppler fetal heart rate monitors for prenatal examinations before 15 weeks of pregnancy. Pregnant women between 15 and 28 weeks of gestation need to have a prenatal check-up every 4 weeks. Pregnant women between 28 and 36 weeks of gestation need to have prenatal checkups every two weeks. For high-risk pregnant women after 35 weeks of pregnancy (for example, pregnant women with gestational hypertension, hyperthyroidism, etc.), they should be hospitalized and have the fetal heart rate continuously monitored using a fetal heart rate monitor. If necessary, continuous monitoring can be provided for a long time (more than 1 hour).

How to judge fetal growth retardation in early pregnancy

Normally, between 16 and 20 weeks of pregnancy, the fetus begins to have noticeable fetal movements that can be felt by the mother, and as the gestational age increases, the fetal movements also increase.

Symptoms of fetal growth retardation also include unexplained abdominal pain: during pregnancy, pregnant women may feel mild abdominal pain at certain stages, which is generally normal. But if the abdominal pain is sudden and crampy, it needs to be taken seriously. In early pregnancy, severe lower abdominal pain accompanied by vaginal bleeding may be a warning sign of ectopic pregnancy or threatened miscarriage.

Symptoms of fetal growth retardation may also be chromosomal abnormalities. If the chromosomes are abnormal, it will also lead to embryonic failure and early miscarriage. Chromosome abnormalities include quantitative and structural abnormalities. Quantitative abnormalities can be divided into aneuploidy and polyploidy. The most common abnormal karyotype is triploidy, and trisomy 16 accounts for 1/3, which is often lethal.
