Meconium is the earliest stool of a mammalian infant resulting from defecation.Unlike later feces, meconium is composed of materials ingested during the time the infant spends in the uterus: intestinal epithelial cells, lanugo, mucus, amniotic fluid, bile, and water.
The mucus plug may become dislodged days before labour begins or not until the start of labour. [38] While inside the uterus the baby is enclosed in a fluid-filled membrane called the amniotic sac. Shortly before, at the beginning of, or during labour the sac ruptures.
Amniotic fluid is mildly basic (pH 7.1–7.3) compared to normal vaginal secretions which are acidic (pH 4.5–6). [10] Basic fluid, like amniotic fluid, will turn the nitrazine paper from orange to dark blue.

The fetal membranes separate maternal tissue from fetal tissue at a basic mechanical level. The fetal membrane is composed of a thick cellular chorion covering a thin amnion composed of dense collagen fibrils. The amnion is in contact with the amniotic fluid and ensures structural integrity of the sac due to its mechanical strength.
During pregnancy, the fetus is protected from sexual thrusting and unwanted semen by the amniotic fluid in the womb and by the cervical mucus plug in the woman's cervix, which forms shortly after conception. [8] [9]
