Xiao Li is pregnant for half a year, often before menstruation to test the pregnancy test stick, it is not easy to have a shallow two bars, overjoyed, full of joy to go to the hospital blood test, HCG has also been elevated, more convinced that they are pregnant...
As a result, within a few days, the bleeding was taken, the blood test was done again, the HCG had come down, and then the biochemical pregnancy was told. Xiao Liu panicked and was very puzzled: What is biochemical pregnancy in the end? Is it a miscarriage?
Birthing pregnancy
Refers to the embryo has begun to implant, nourishing the ectoderm invading the deciduous layer of the uterus, the embryo secreted β-HCG into the maternal blood and reached a detectable level, but then for some reason, the pregnancy does not continue, the β in the blood or urine - HCG is only a transient elevation, the pregnancy is only carried out to the stage that can be detected by biochemical methods, and does not develop to the stage that can be diagnosed with ultrasound, which can be regarded as a special type of early pregnancy loss.
Biochemical pregnancy is a type of early embryo loss, which is different from what we usually call miscarriage. Miscarriage refers to clinical pregnancy loss and refers to termination of pregnancy that occurs after implantation, while biochemical pregnancy is a failure of implantation.
Therefore, although both biochemical pregnancy and miscarriage fall under the category of embryo or pregnancy loss, they occur at different physiological stages, so the two are not the same thing.
1. Why biochemical pregnancy?
So why does biochemical pregnancy occur? There are mainly the following reasons:
1 The fertilized egg itself is defective: It is generally believed that chromosomal abnormalities in the embryo may be the main cause of biochemical pregnancy. More than 50% of early miscarriages in the first trimester of pregnancy are due to chromosomal abnormalities.
2 Poor ovarian corpus function: insufficient progesterone secretion, abnormal endometrium, affecting implantation of fertilized eggs.
3 Uterine factors: uterine dysplasia, uterine submucosal fibroids, endometrial polyps, uterine cavity adhesions, endometrial tuberculosis, etc. affect the implantation of fertilized eggs.
4 Immune factors: There are two immune conditions that affect conception.
One is alloimmunity: sperm, seminal plasma or fertilized eggs are antigenic substances, which are absorbed by the vagina and uterine epithelium, and produce antibody substances through immune responses, so that sperm and eggs cannot be combined or fertilized eggs cannot implant;
The other is autoimmunity: it is believed that there are zona pellucida autoantibodies in the serum of infertile women, and that reacting with the zona pellucida prevents sperm from penetrating the egg and thus prevents fertilization.

5 Excessive mental stress: especially severe anxiety due to infertility, psychological pressure is too great.
6 External factors: smoking (including smoking second-hand smoke), alcohol consumption, exposure to chemical poisons, severe noise and vibration, emotional agitation, high temperature environment, etc.
7 Infection during pregnancy: Infected with bacterial viruses during pregnancy, affecting embryonic development.
In fact, biochemical pregnancy is essentially a natural choice of survival of the fittest, if you encounter such a situation by chance, you do not have to be too anxious, nor do you need to do any treatment and treatment, and generally will not affect the next pregnancy.
However, if this happens many times, it is necessary to go to the hospital for further detailed examination, find out the cause, and targeted treatment.
2. How to avoid biochemical pregnancy?
Those couples who are eager for children, have done enough preparation homework but have not been satisfactory, we must avoid the occurrence of a spontaneous abortion that is difficult to conceive a baby and hastily, and what should we do if we want to avoid biochemical pregnancy?
1 Contraception should be used within half a year after the occurrence of miscarriage, and pregnancy again after half a year can reduce the occurrence of miscarriage.
2 To do a genetic test, both husband and wife undergo chromosome tests at the same time.
3 Blood grouping, including Rh blood grouping.
4 If there is a loose uterine orifice, an inlet suture can be done.
5 Drugs for the treatment of luteal insufficiency should be used for longer than the gestation period of the last miscarriage, if the last abortion was in 3 months of pregnancy, the treatment time should not be less than 3 months from the beginning of pregnancy.
6 Hypothyroidism, wait for thyroid function to return to normal before pregnancy, pregnant also need to take anti-hypothyroidism drugs.
7 Emotional stability, regularity of life.
8 Avoid exposing yourself to noisy, heavily polluted environments (including second-hand smoke).
9 Avoid exposure to toxic and radioactive substances.
How long after a biochemical pregnancy can I get pregnant again? There are no special regulations in this regard, just repeat the check on time, the HCG value drops to normal, and you can try to conceive again.
If you are not particularly anxious to have a child, you can also consider suspending the preparation for pregnancy for a period of time, so that the uterus has enough time to "rest", improve the bad condition that leads to miscarriage, and get rid of the external environment that is unfavorable to embryonic development.
I wish everyone a good pregnancy in the Year of the Tiger and a happy tiger treasure
