What exactly is biochemical pregnancy? Does it have a bad effect on the body? Will it affect subsequent pregnancies? Today, we will take a look at the "biochemical pregnancy" that does not have a low incidence and does not know many people.
What is biochemical pregnancy?
Normal pregnancy is when the sperm and egg combine in the fallopian tube to become a fertilized egg, and the fertilized egg returns to the uterus to implant, and then further develops into a fetus.
Biochemical pregnancy is when sperm and egg are combined, but do not return to the uterus to implant, or enter the uterus, do not implant.
Biochemical pregnancy meets the following three characteristics:
1. Blood hCG value is generally not high, continuous monitoring not only does not double, but also has a downward trend, and progesterone value is low;
2. Ultrasound B cannot see the gestational sac inside and outside the uterine cavity;
3. There may be bleeding, abdominal pain and other symptoms.
Biochemical pregnancy is clinically presented with urine or blood hCG reaching a detectable level, but only a transient elevation, the pregnancy sac cannot be seen on ultrasound, and then the pregnancy status is naturally terminated.
Why biochemical pregnancy?
Many women who are not planning to conceive do not specifically test HCG, so even if there is a biochemical pregnancy, they only think that the great aunt has postponed coming for a few days.
Biochemical pregnancy tends to occur when:
1. The fertilized egg itself is defective. More than 50% of early miscarriages in the first trimester of pregnancy are due to chromosomal abnormalities.
2. The function of ovarian corpus luteum is not good. Poor luteum, resulting in insufficient progesterone secretion and abnormal endometrium, can affect the implantation of the fertilized egg in the womb.
3. Uterine factors. Uterine dysplasia, uterine submucosal fibroids, endometrial polyps, uterine cavity adhesions, etc. will affect the implantation of the fertilized egg.
4. Immune factors. There are two immune conditions, isoimmunity and autoimmunity.
5. Excessive mental tension. Especially because of severe anxiety due to not being pregnant, psychological pressure is too great.
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.
Are biochemical pregnancies and miscarriages the same thing?
Both biochemical pregnancy and miscarriage are pregnancy failures, but the two are not the same thing.
Biochemical pregnancy, which is a stage of pregnancy that is only carried out to the point where biochemical methods can be detected, can be regarded as a special type of early pregnancy loss.
Miscarriage, an event that occurs after the implantation of the embryo, is the loss of a clinical pregnancy.
Thus, while both biochemical pregnancy and miscarriage fall under the category of embryo or pregnancy loss, occurring at different physiological stages is not the same thing.
How long after a biochemical pregnancy can I get pregnant again?
There are no special contraindications, but it is still necessary to pay attention to vaginal bleeding and abdominal pain, it is advisable to monitor the blood hCG to fall to normal, and avoid immediate conception before returning to normal, because it is impossible to distinguish whether a pregnancy is not over or whether the "baby" is coming. If you have 2 to 3 normal menstruations, you can try to conceive.
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" to improve its own adverse conditions that lead to miscarriage and get rid of the external environment that is unfavorable to embryonic development.
Biochemical pregnancy is a natural process of embryo elimination, do not be too nervous or regretful. Its pregnancy time is short, there is no implantation, the injury is small, the prognosis is good, generally will not affect the next pregnancy, and does not require special treatment. However, if there are multiple consecutive biochemical pregnancies, you should go to the hospital for systematic examination, find the cause, and treat the symptoms.
