What does fetal biochemistry mean?

As we all know, pregnancy begins with the fusion of sperm and egg into sperm-egg combination. On the 7th day of fertilization, the sperm-egg combination will immediately split into the trophoblast, which is the future embryo, and then it will secrete chorionic gonadotropin. At the same time, the sperm-egg combination will also move from the fallopian tubes to the uterine body and embed into the uterine wall. HCG can be detected on the 10th day after fertilization, and pregnancy can be detected on the 14th day after fertilization. A normal pregnancy can not only detect HCG, but also see the fetal sac. However, the gestational sac cannot be seen during pregnancy biochemistry.

What does pregnancy biochemistry mean?

Biochemical pregnancy refers to early pregnancy miscarriage within 5 weeks of pregnancy. Although HCG levels can be detected in the blood and the urine pregnancy test is positive, if the color Doppler ultrasound is performed, the gestational sac cannot be seen, which indicates that the embryo has not implanted successfully. Therefore, ectopic pregnancy is also called "subclinical miscarriage". To put it simply, ectopic pregnancy refers to a situation in which the sperm and egg combine but do not return to the uterus for embryo implantation.

reason

It is generally believed that the causes of ectopic pregnancy are the same as those of spontaneous abortion. Chromosomal abnormalities in test tube embryos and defects in sperm-egg fusion are all biochemical causes. However, incomplete ovarian corpus luteum function, insufficient progesterone metabolism, and endometriosis can also affect embryo implantation. In addition, if a woman has uterine hypoplasia, uterine cervical fibroids, endometrial polyps, intrauterine adhesions, uterine wall fusion, etc., it will also affect embryo implantation.

Ectopic pregnancy is to some extent a theory of natural selection of the survival of the fittest. Therefore, if women of childbearing age encounter this situation, they must not panic, and ectopic pregnancy will not affect the next pregnancy, unless this situation occurs several times, it will be necessary to see a doctor for further examination.

disease

Generally, if it is an ectopic pregnancy, the early pregnancy test can detect a weak positive, but it is impossible to detect a positive, let alone a strong positive. In addition, no fetal sac can be seen in the uterine cavity during B-ultrasound examination. And the blood HCG will be very low, which only indicates pregnancy, but cannot indicate whether implantation is successful. In addition, ectopic pregnancy generally will not abort immediately after more than 50 days, at which time gray film-like cargo will continue to flow out of the vagina.

Frequently Asked Questions about Pregnancy Biochemistry

Ectopic pregnancy is caused by the combination of sperm and egg without embryo implantation, so there is no damage to the uterus. You can also think of it as your period being late this month, so there's no need to worry too much. Generally speaking, after an ectopic pregnancy occurs, you need to pay attention to the following:

Regular maintenance

Ectopic pregnancy does not require uterine cleaning, but blood HCG should be maintained regularly to determine whether the gestational sac is alive, in other words, whether it has been expelled from the body. Once it is confirmed that the blood HCG has dropped to normal levels, you can plan your next pregnancy.

Days to get pregnant again

If the B-ultrasound shows that you are in good health, you can have a baby the next month or in three months. However, it is still recommended not to have sex immediately after an ectopic pregnancy. It is best to let the uterus rest.

Diet level

After the end of pregnancy, you can eat more fish, meat, eggs, and beans in your diet. These foods rich in protein and vitamins can speed up the body's recovery.
