But if the brown discharge continues for more than a few weeks accompanied by some discomfort, you should consult a doctor.

Causes of the brown discharge during pregnancy:

  • Implantation bleeding is brown and very scanty. Brown discharge might take place when a fertilized egg gets attached to the lining of the uterus.
  • During pregnancy the hormonal level changes which make the area around the vagina and cervix very itchy and irritable. Due to the fluctuations of hormones, the area can become sensitive.
  • Irritation of the cervix due to sexual intercourse can also cause BD during pregnancy. The cervix has extensive blood supply pooling in during pregnancy that makes it very sensitive.
  • Cervical or vaginal infection can be a cause of brown discharge.
  • Brown discharge might be an indication that labor and delivery are around the corner. When you cross the 36 or 38-week pregnancy, the mucus plug can come off. The loosening of cervix allows brown or pinkish brown discharge to come out.

Complications and reasons to worry about brown discharge during pregnancy

  • Miscarriage: In sporadic cases, a brown discharge may also mean that there is a miscarriage. If heavy brown discharge continues for a few days, along with extreme discomfort and pain, consult a doctor.
  • Ectopic pregnancy: It is a severe condition and another one of the causes of brown vaginal discharge. Usually, a fertilized egg gets attached to the lining of the uterus where its development starts. But in the case of ectopic pregnancy, the development of the embryo begins in the fallopian tube. This condition can cause a threat to the lives of both the baby and the mother. Stomach pain and cramps can be an indicator of such a situation.
  • Infection and inflammation: Brown discharge can occur in the case of vaginal infection that can cause harm to the baby. Mommies may feel itchiness and irritated.
  • Placental abruption: During this, the placenta gets separated from the uterus prematurely, this causes the vagina to bleed.

Another event in late pregnancy is the loss of the mucus plug from the cervix. The mucus plug seals the vagina in the early months of pregnancy. When parturition is near the mucus plug falls off.

The old blood might come along the vaginal discharge. It is the brown vaginal discharge during third-trimester pregnancy.

Brown discharge with a low placenta

If you have a low lying placenta, the blood vessels might rupture and cause internal bleeding under pressure. A low lying placenta leaves very less subchorionic space.

All this causes frequent internal bleeding. This changes the cervical discharge to pinkish brownish discharge during pregnancy. Later this becomes dark brown discharge during pregnancy.

  6. I’ve been diagnosed with low placenta and have had light brown discharge for 5 days. Three day prior I had dark brown to red , that’s when I was diagnosed . I am 14 weeks.

    • That’s a very good idea, to keep a check, because pregnancy has concerns. I’d suggest to take time off feet. If you’re a working mom try sitting down while working. If that isn’t possible cut down daily chores other than compulsory work. Eat well and keep calm. If your doctor said there’s nothing to worry about then you can rely or maybe get another consultation for second opinion. Wear loose clothes but always support your belly even at 14 weeks.
