A fertilized egg is like a seed. After a series of complicated and wonderful processes, it will eventually grow into a healthy baby. If the fertilized egg does not germinate well in the initial stage, it is likely to stop growing healthily. We call this phenomenon of abnormal embryonic development in the first trimester "fetal arrest".
"Abortion" is different from abortion in the second and third trimester. It stopped developing before the embryo was formed.
According to the survey, many expectant mothers don't know that they have terminated their pregnancy during pregnancy. Will there be a signal for abortion? Generally, there are the following five types:
First, the HCG level decreased.
Human chorionic gonadotropin (HCG) is a hormone produced only in pregnant women. It is because of this hormone that pregnancy tests show positive pregnancy results. Although HCG level fluctuates all the time during pregnancy, lower than normal level may be a sign of fetal growth and development problems.
If the pregnant mother finds that the HCG level is lower than normal, please don't arrange observation at home at will, and go to the hospital for treatment in time.
Second, the fetus has no heartbeat.
One of the most obvious and direct signs of fetal problems is that the heartbeat cannot be obtained. The fetal heart can be heard from 9-10 weeks of pregnancy. As time goes on, the heart will get stronger and stronger. Therefore, if a pregnant mother feels that she can't hear her baby's heartbeat, please consult a doctor immediately.
Third, unbearable cramps.
Belly cramps during menstruation are another matter, but if a woman starts cramping during pregnancy, it means the baby is in trouble. From a medical point of view, if the expectant mother has convulsions during pregnancy, it means that there may be problems with the baby's health and it is necessary to seek medical attention in time.
Fourth, the uterus is highly dysplasia
The height of the uterus is the height from the top of the uterus to the pubic bone. Measuring with adhesive tape can help doctors ensure that the uterus and the fetus grow together. If the measurement results are not in line with expectations, it may be a sign of abnormal fetal development.
5. The fetus is still or low.
Pregnant mothers will begin to feel the fetus moving in the uterus in the second trimester of pregnancy, which is what we often say. Fetal movement is a sign of health, but if the pregnant mother does not feel fetal movement, or the frequency of fetal movement is significantly reduced than before, then the fetus may be in trouble.
There are many reasons for fetal arrest. There are five common reasons:
1, reproductive endocrine problems, early embryonic development needs three important hormones, if the mother's own endogenous hormones are not enough, it will cause embryo termination. This is the focus of traditional fetal protection.
2, uterine problems, mainly uterine environment, uterine mediastinum and other problems, BC, hysteroscopy can be done.
3, chromosome problems, both husband and wife blood tests, this can be simply ruled out.
4. The problem of reproductive immunity can be divided into autoimmune type and allotype. The corresponding examination is more complicated and most doctors don't understand it.
5, the mother's own coagulation problems, hypercoagulable state forms a prethrombotic state, affecting the blood flow of uterine arteries, leading to insufficient blood supply to the placenta, which will also cause the baby to be bad.
Although there are various precautions during pregnancy, it is also important to maintain a good and cheerful attitude. Check regularly and respect the doctor's advice to relax.
