Is It Normal to Have Brown Discharge During Pregnancy?

Update Date: Source: Network

Brown menstrual blood during the first month of pregnancy is an abnormal phenomenon, which may be caused by ectopic pregnancy, trichomonas vaginalis infection, threatened abortion, and other reasons. Here are some details:

1. Ectopic Pregnancy

Ectopic pregnancy usually manifests as vaginal bleeding around 40 days after menstruation stops, often accompanied by dull pain, distention, and dragging pain in the lower abdomen. Urine pregnancy tests may be positive at this time, but ultrasonography will not show a gestational sac in the uterine cavity. Instead, abnormal masses may be found in the fallopian tubes.

2. Trichomonas Vaginalis Infection

This infection can cause an increase in vaginal discharge, accompanied by a foul odor and itching in the vaginal area. It is generally considered a sexually transmitted infection and can easily be transmitted between partners. To achieve complete cure and prevent cross-infection, both partners must be treated simultaneously.

3. Threatened Abortion

During the threatened abortion stage, vaginal bleeding is typically minimal, and abdominal pain is mild. If there is no abnormal embryonic development, bleeding will stop after treatment to preserve the pregnancy, and the pregnancy can continue. While menstruation cessation is the most common sign of pregnancy, not all pregnancies result in menstruation cessation. Some women may continue to have menstrual bleeding during pregnancy due to low levels of sex hormones, especially progesterone, secreted by the ovaries, causing a small portion of the endometrial lining to continue to shed. However, the amount of menstrual bleeding during pregnancy is typically much less than during a normal menstrual cycle. After three months of pregnancy, when the placenta forms and maintains relatively high levels of estrogen and progesterone in the woman's body, the endometrial lining no longer sheds, and menstruation ceases. Therefore, although some women may still experience menstrual bleeding during pregnancy, this is closely related to hormonal levels in the body. However, brown menstrual blood during the first month of pregnancy is an abnormal phenomenon that may indicate threatened abortion, infection, or ectopic pregnancy. In such cases, it is recommended to seek medical attention for a definitive diagnosis.
