The probability of a miscarriage at four months of pregnancy

A problem that many women are particularly worried about during pregnancy is fetal growth retardation. The probability of fetal growth retardation in women is higher in the early stages of pregnancy. There are also many clinical reasons that may cause fetal growth retardation in women, such as the woman's physical constitution, disease factors, etc., which may all lead to fetal growth retardation. When you are 4 months pregnant, you have already passed the early stage of pregnancy. So what is the probability of fetal arrest in 4 months of pregnancy?

1. There is no complete statistical data on the probability of fetal arrest at four months of pregnancy. Generally, the probability of spontaneous abortion before 28 weeks of pregnancy is 31%. Most spontaneous abortions occur in the early stages of pregnancy, that is, in the first three months. The later the pregnancy progresses, the lower the probability of fetal arrest and fetal death. During pregnancy, you should pay attention to eating a light and balanced diet, try to avoid all adverse factors that may affect the fetus, and do a good job of prenatal examinations and screening.

2. Under normal circumstances, the embryonic development is relatively stable after 4 months of pregnancy, and it is not easy to experience fetal arrest or threatened abortion. Generally, the early stage of pregnancy, that is, the first 3 months of pregnancy is very critical. During this period, the embryo is prone to arrest and threatened abortion may occur. You must go to the hospital for relevant examinations and then receive symptomatic treatment. For most people, there are no major problems after 4 months of pregnancy. If there are abnormalities, such as chromosomal abnormalities or hemolytic problems, the embryo may arrest. If there is a viral infection in the body, the fetus may also stop developing. Before preparing for pregnancy, you need to go to the hospital for regular check-ups. It is better to prepare for pregnancy when all your body functions are normal. Therefore, the chance of fetal arrest at 4 months of pregnancy is very small. During pregnancy, you generally need to do relevant check-ups. If there are any abnormalities, you should receive symptomatic treatment in time.

3. At four months of pregnancy, the fetus has been formed and the placenta has grown, so the placenta directly supplies nutrients to the fetus. At this time, it is generally not easy to be affected by external factors and cause fetal arrest, so the probability of fetal arrest is very low, generally less than 10%. Just be careful to protect your abdomen at this time to avoid external impact on the abdomen, which may cause placental abruption and lead to intrauterine fetal death. If the fetus itself has deformities at this time, fetal arrest usually will not occur immediately. Organ deformities usually do not appear until after 24 weeks of pregnancy.
