When your mucus plug comes out, it means that your cervix is beginning to dilate (open) and your body is preparing for labor. The mucus plug is a thick, jelly-like collection of mucus that forms in the cervical canal early in pregnancy to block bacteria and protect the uterus and fetus from infection. As the cervix softens and opens in preparation for birth, the mucus plug is expelled
. The mucus plug can come out all at once as a large glob or in smaller pieces over time. It is usually thick, sticky, and may be clear, off-white, or tinged with blood, giving it a pink, red, or brown color. This blood-tinged mucus is sometimes called the "bloody show" and is a normal sign that labor may be approaching
. Losing the mucus plug does not necessarily mean labor will start immediately; labor could still be hours, days, or even weeks away. However, it is a key sign that your body is getting ready for labor. If you experience heavy bleeding or other unusual symptoms after losing your mucus plug, you should contact your healthcare provider
. In summary, losing your mucus plug means your cervix is opening in preparation for labor, signaling that birth is approaching, but it does not guarantee that labor will start right away
