What is the cause of brown discharge at 50 days of pregnancy?

A pregnant woman found brown discharge at 50 days of pregnancy and was worried whether there was something wrong with her fetus. Brown discharge in early pregnancy needs to be taken seriously, because it may be unstable in the early pregnancy period and may be an abnormality caused by miscarriage. Therefore, pregnant women should pay more attention to their physical condition and check in time if there are any abnormal symptoms.

Why is there brown discharge after pregnancy? Common causes of brown discharge in early pregnancy include the following:

1. Biochemical pregnancy Biochemical pregnancy means that the sperm and egg have combined, but have not swam into the uterine cavity to implant, or have swam back and failed to implant successfully, which is called "hidden abortion." Generally, in the case of miscarriage within 5 weeks of pregnancy, HCG can be detected in the blood and it is higher than the normal value or the urine pregnancy test is positive, but the gestational sac cannot be seen on ultrasound examination. This is also called "subclinical miscarriage." Patients usually have no other symptoms, just like having their period, so it is often ignored.

2. Abnormal embryonic development. If the fetus develops abnormally, it will lead to spontaneous abortion. Most of them are due to chromosomal abnormalities. Data show that 50-60% of cases of early pregnancy abortion or fetal arrest are due to chromosomal abnormalities. Experts suggest that if brown secretions are found, after excluding abnormal development or lesions of the cervix or other genital organs, you should let nature take its course and do not try to preserve the pregnancy at will, otherwise bigger problems will arise later.

3. The most common cervical abnormality is cervical erosion. If brown discharge appears the next day after sexual intercourse (many people do not know they are pregnant), cervical erosion should be considered. Secondly, cervical polyps can also cause bleeding, and the bleeding will continue. More attention should be paid to decidual polyps, which are polyps unique to pregnancy and are more prone to bleeding than cervical polyps and will continue to bleed for a long time until the second trimester. This type of polyp cannot be surgically removed, otherwise it will cause miscarriage or continuous bleeding. Therefore, if you have brown discharge during early pregnancy, go to the obstetrics and gynecology department to check your cervix first. In cases of malformations such as double uterus or rudimentary horn uterus, after a normal uterus becomes pregnant, the abnormal endometrium will thicken and cause a small amount of bleeding. Therefore, ultrasound examination is essential for early pregnancy bleeding.

4. Endometrial shedding Due to individual differences and other reasons, some women's ovaries secrete relatively low levels of sex hormones, especially progesterone, after pregnancy, causing a small part of the endometrium to continue to shed. Therefore, these women will still have menstruation after pregnancy, but the amount of menstruation will be much less than normal. It is not until three months into pregnancy that the placenta is formed and the estrogen and progesterone levels in the female body are maintained at a relatively high level. At this time, the endometrium no longer sheds and menstruation no longer occurs.

5. Ectopic pregnancy refers to an abnormal pregnancy process in which the fertilized egg implants and develops outside the uterine cavity. Ectopic pregnancy often has irregular vaginal bleeding, which is dark red, small in amount, and continuous, generally not exceeding the menstrual volume. Decidual tubular casts or fragments may be discharged with the vaginal bleeding. Ectopic pregnancy is extremely harmful. Not only can the fertilized egg fail to develop into a normal fetus, but if the symptoms of ectopic pregnancy are not detected and treated early, it may be life-threatening. Therefore, you should still pay attention and go to the hospital for examination immediately if any symptoms occur.
