[Two Bars] Appear and Disappear, What’s the matter? Could it be [biochemical pregnancy]?

Saran is a hard-working white-collar worker with a happy life. In order to welcome the arrival of the little angel, she has been pregnant for 3 months.

This month’s big aunt didn’t come when she was supposed to come. Saran excitedly tested it with early pregnancy test paper and turned out to be a light [mid-team leader]! Just when she was happy to be promoted to be a expectant mother, she didn’t expect her big aunt to visit after two days. Saran went to the hospital for examination. The doctor told her it was a biochemical pregnancy, and she was stunned at once!

Is what a biochemical pregnancy? Will it affect the pregnancy afterwards? Next, Luo Xuezhen, deputy chief physician of Fudan University’s Affiliated Obstetrics and Gynecology Hospital, will tell you about [biochemical pregnancy], which has a high incidence rate but few people know about it.

What is a biochemical pregnancy?

Biochemical pregnancy refers to the loss of pregnancy within 5 weeks of pregnancy, which is caused by the failure of implantation of fertilized eggs. It is characterized by elevated hCG in blood, more than 25 mlU/mL or positive urine pregnancy test, but no gestational sac can be seen by ultrasound examination, which is now also called [subclinical abortion] in medicine.

Biochemical pregnancy is not uncommon, accounting for about 25% ~ 30% of the total pregnancy. If hCG is not specially detected, some female friends may just think that their great aunt has postponed her arrival once and will not realize that this is a biochemical pregnancy.

Is biochemical pregnancy abortion?

No. According to medicine, biochemical pregnancy is a very early abortion, but it is not the same as what people usually call abortion.

    Biochemical pregnancy: It is a special type of early pregnancy loss that only goes on to the stage that can be detected by biochemical methods and does not develop to the stage that the gestational sac can be diagnosed by ultrasound. Abortion in the general sense: An event that occurs after embryo implantation is the loss of clinical pregnancy.

Biochemical pregnancy and abortion belong to the category of embryo or pregnancy loss, but they occur in different physiological stages and are different.

Causes of biochemical pregnancy

Normal pregnancy is when sperm and egg combine in the fallopian tube to form a fertilized egg, Fertilized eggs return to the uterus for implantation and can further develop into fetuses, which is equivalent to burying seeds in the soil to continue to develop. Biochemical pregnancy is a combination of sperm and eggs, but they do not return to the uterus for implantation, or enter the uterus and do not go to bed. Simply put, the seeds have not been successfully planted in the soil.

Biochemical pregnancy is easy to occur when the following conditions occur:

  1. The fertilized egg itself has defects: It is generally believed that chromosome abnormalities of embryos may be the main cause of biochemical pregnancy. Chromosome abnormalities account for more than 50% of early abortions in the first three months of pregnancy.

  2. Ovarian corpus luteum function is not good: corpus luteum is not good, resulting in insufficient progesterone secretion and abnormal endometrium, which will affect the implantation of fertilized eggs in the uterus.

  3. Uterine factors: uterine dysplasia, submucosal leiomyoma, endometrial polyps, intrauterine adhesions, endometrial tuberculosis and other factors affect the implantation of fertilized eggs.

  4. Immune factors: Due to the immune system, women produce antibodies against fertilized eggs, which prevent fertilized eggs from implanting.

  5. Excessive mental stress: especially serious anxiety and excessive psychological pressure caused by not being pregnant.

In the normal process of fertilization and implantation, biochemical pregnancy refers to the production of fertilized eggs but no implantation in the uterus.

Biochemical pregnancy is essentially a natural selection for survival of the fittest. If you encounter such a situation, you don’t need to be too nervous, don’t need any treatment and treatment, and generally won’t affect the next pregnancy. If such a situation occurs many times, it is necessary to go to the hospital for further detailed examination, find out the cause of the disease, and carry out targeted treatment.

How long can biochemical pregnancy be pregnant again?

After the biochemical pregnancy, There is no need to specially recuperate the body. As long as you have a good rest, don’t overwork, and relieve mental pressure through self-regulation. There is no special regulation on how long will it take to get pregnant again after biochemical pregnancy. If you are not particularly anxious to have a child, you can consider resting for 3-6 months, so that the uterus has enough time [rest] to meet the arrival of the baby in the best state.
