When you’re nearing the end of your pregnancy, every little change in your body can feel like a sign that labor is just around the corner. One of these signs is losing your mucus plug. But what exactly is a mucus plug, and more importantly, how long after losing your mucus plug does labor actually start? Here’s what you need to know from the experts.
What is the Mucus Plug and Why Do You Lose It?
During pregnancy, your body works to create a safe and protective environment for your developing baby. One of the ways it does this is by forming a mucus plug. This plug is a thick collection of mucus that seals the cervical canal, which is the opening to your uterus from your vagina. Think of it as a barrier that helps to keep bacteria and infection out of the uterus, protecting your baby. According to Kristin Mallon, CNM, a certified nurse midwife, this mucus plug is a vital defense mechanism throughout your pregnancy.
As you approach your due date, your body begins to prepare for labor. Adeeti Gupta, MD, an OB-GYN, explains that hormonal changes cause the cervix to soften and start to dilate, or open. These changes, along with mild uterine contractions, can cause the mucus plug to loosen and be expelled from the vagina.
You might notice the mucus plug as a jelly-like blob, often described as looking like nasal mucus. It can vary in color, appearing yellowish-white, or tinged with pink, red, or brown blood. This blood is often referred to as “bloody show” and is a result of small capillaries in the cervix rupturing as it softens and dilates. However, some people may not notice losing their mucus plug at all, as it can sometimes be passed without you realizing it, or it might come out gradually.
Losing the Mucus Plug: Is Labor Imminent?
The loss of your mucus plug is indeed a sign that things are starting to progress towards labor. The American College of Obstetricians and Gynecologists (ACOG) confirms that the mucus plug is expelled as the cervix begins to dilate in preparation for childbirth. So, in essence, losing your mucus plug is a signal that your body is gearing up for labor.
However, it’s crucial to understand that losing your mucus plug doesn’t necessarily mean labor will start immediately. Kristin Mallon, CNM, points out that while losing the mucus plug, especially with some blood, is often a good indication that labor is coming within one to three days, this isn’t always the case. For some individuals, labor might begin weeks after the mucus plug is released. Therefore, while it’s an encouraging sign, it’s not a precise predictor of when labor will begin.
How Long After Losing Your Mucus Plug Does Labor Typically Start?
The timeframe between losing your mucus plug and the onset of labor is highly variable. For some pregnant individuals, labor might start within hours of noticing the mucus plug. For others, it could take days or even weeks. There’s no set rule, and every pregnancy is different.
It’s also important to remember that even after you lose your mucus plug, your baby remains protected. Dr. Clara Ward, a maternal-fetal medicine specialist, reassures that the cervix continues to produce mucus, replenishing what was lost. Furthermore, the amniotic fluid itself contains immunological agents that continue to safeguard the baby from infection.

What Should You Do After Losing Your Mucus Plug?
Discovering that you’ve lost your mucus plug can be exciting, but it’s not necessarily a signal to rush to the hospital immediately. Instead, it’s a good time to start paying close attention to other signs of labor. These signs include:
- Contractions: These will become progressively longer, stronger, and closer together.
- Consistent Contractions: Labor contractions will continue even if you change positions or move around.
- Back to Front Contraction Pain: Labor pain often starts in the back and radiates to the front of your abdomen.
- Lightening: This is the sensation of the baby dropping lower into your pelvis.
- Water Breaking: This is the rupture of the amniotic sac, and it can feel like a gush or a slow leak of fluid.
If you notice any of these signs of labor, it’s advisable to contact your healthcare provider. If it’s not urgent or during office hours, and you’ve only lost your mucus plug, you can inform them the next day or at your next scheduled appointment, as suggested by Kristin Mallon, CNM. In the meantime, it’s wise to monitor your baby’s movements and stay aware of any other changes in your body.
Dr. Gupta recommends timing your contractions if they begin. When contractions become regular, lasting for at least 30 seconds and occurring every three to five minutes, it’s generally time to consider going to the hospital. You should also head to the hospital if your water breaks.
There’s an important exception: If you lose your mucus plug before your 37th week of pregnancy, it’s crucial to contact your healthcare provider promptly. Losing your mucus plug prematurely might not always be a cause for alarm, especially if it’s not your first pregnancy. However, it could be a sign of preterm labor, and your provider will want to assess the situation and advise you on any necessary steps to take.
Keep Watch for Other Signs of Labor
After losing your mucus plug, being attentive to other labor indicators is key. Dr. Ward mentions “lightening,” the sensation of the baby descending, as another sign. While this might increase pelvic pressure, it can also make breathing feel easier.
Some individuals may experience increased cramping or back pain as labor contractions begin. You might also feel more tired than usual or notice a feeling of looseness in your joints.
Healthcare providers can assess cervical dilation to determine labor progression. Interestingly, there’s also a visual cue called the “purple line,” a line of discoloration that may appear on the buttocks during labor. Research indicates this line can be present in about 75% of pregnant individuals in labor and can be a non-invasive way to gauge labor progress.
Ultimately, staying calm and informed is essential. Dr. Ward advises that if you are full-term (beyond 37 weeks), there’s likely no need to contact your doctor immediately after losing your mucus plug unless you experience heavy bleeding, regular contractions, foul-smelling mucus, or suspect your water has broken. Also, watch out for fever or greenish or yellowish amniotic fluid discharge.
If you have any concerns or uncertainties, it’s always best to reach out to your healthcare provider for reassurance and guidance. They are there to support you and ensure a safe and healthy delivery for you and your baby.
