Yellow or green discharge
Yellow or green discharge is often a sign of sexually transmitted diseases such as chlamydia, trichomoniasis, and gonorrhea. STD during pregnancy and before labor must be addressed immediately as the infection poses a risk to both the mother and the baby. If the condition is not treated right away, it can lead to complications during and after birth.
Gray, watery discharge that comes with a foul, fishy smelly is typically a symptom of bacterial vaginosis. If a pregnant woman acquires bacterial vaginosis a few months or weeks before labor, her risk of preterm labor and low birth weight increases.
Pregnant women have more sensitive reproductive organs. That is why sexual intercourse or a pelvic exam while pregnant may cause irritation, resulting in dark or light brown discharge or light spotting.
Light spotting is usually not alarming, but it might also be a sign of labor if the mucus plug releases itself from the cervix. Thus, it is best to consult the doctor right away to prevent any surprises.
Whitish-pink or pink discharge
A whitish-pink or pink discharge (bloody show) in the later weeks of the third trimester is a common sign that a pregnant woman is about to go into labor. However, a pink discharge in the early stages of pregnancy can be worrying, as it it can be a sign of an upcoming miscarriage or ectopic pregnancy.
Red or bloody vaginal discharge during the third trimester that is heavy and comes with clots, abdominal pain, or cramping suggests a serious pregnancy problem, such as preterm birth.
