Brown discharge during early pregnancy

Pregnancy is an important period for women. During this whole month, women must take good care of their bodies and not let any problems occur. Pregnant women may have brown discharge and leucorrhea in the early stages of pregnancy. In this case, you must be careful, as it may be a biochemical disorder or uterine disease, which also includes abnormal embryonic development.

What causes brown discharge during pregnancy?

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 successfully implant, 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 cause spontaneous abortion, most of which 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. Cervical abnormalities

The most common cervical erosion is that if brown discharge occurs the day after sexual intercourse, 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

It refers to the 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.
