Losing your mucus plug means your cervix is changing, but it doesn’t mean labor is imminent. Some people go into labor within hours, others wait days, and for some it takes a few more weeks. There’s no guaranteed way to make labor start on your timeline, but several approaches may help your body move things along once this process has begun.
What Losing the Plug Actually Tells You
The mucus plug seals the opening of your cervix throughout pregnancy, protecting the baby from bacteria. When it comes out, it means your cervix has started to soften, thin, or open. That’s a real, measurable change, but it’s an early step in a longer process. Your body still needs to release enough prostaglandins (natural chemicals that soften and open the cervix further) and eventually ramp up contractions strong enough to dilate you fully.
Pay attention to what the discharge looks like. If it’s mostly clear or yellowish and jelly-like, that’s a standard mucus plug. If it’s streaked with blood or mixed with pink, red, or brown discharge, that’s called “bloody show,” and it’s a stronger signal. Bloody show happens because your cervix is actively thinning and widening, which irritates the blood vessels there. It typically means labor is closer, though “closer” could still mean hours or days.
Movement and Positioning
Walking hasn’t been proven to trigger labor in studies, but staying upright and active serves a different purpose: gravity helps your baby’s head drop deeper into the pelvis. That downward pressure on the cervix can prompt your body to release more prostaglandins, the same chemicals your body uses naturally to ripen and open the cervix.
Curb walking takes this a step further. By stepping one foot on and off a curb, you create an uneven movement in your pelvis. The theory is that this asymmetry encourages the baby’s head to descend and engage more firmly against the cervix, increasing pressure where it matters. There’s no clinical trial confirming it works, but the biomechanics are sound and the risk is essentially zero as long as you’re steady on your feet.
Other movements worth trying:
- Squats and lunges open the pelvis and help engage the baby’s head lower.
- Birthing ball exercises like sitting, gently bouncing, or doing hip circles can encourage the baby to move downward while relieving pelvic tension.
None of these will force labor to start if your body isn’t ready, but they put you in positions that support the process already underway.
Nipple Stimulation
This is one of the few natural methods with a clear biological mechanism. Nipple stimulation causes your body to release oxytocin, the same hormone hospitals use (in synthetic form) to induce labor. Oxytocin triggers uterine contractions.
The catch is that it can work too well. Nipple stimulation can sometimes cause prolonged, intense contractions that reduce blood flow to the baby. OB-GYNs at UT Southwestern Medical Center have noted this risk and generally don’t recommend it as a self-directed induction method. If you want to try it, keep sessions short (a few minutes at a time) and stop if contractions become painful or very frequent. This is one to discuss with your provider first.
Sexual Intercourse
The logic behind sex as a labor starter sounds reasonable: semen contains natural prostaglandins, orgasm releases oxytocin, and both of those chemicals play roles in cervical ripening and contractions. In practice, the evidence is mixed. At least one study found that sex near your due date might actually reduce the likelihood of going into labor. It won’t hurt (assuming your water hasn’t broken and your provider hasn’t told you to avoid it), but don’t count on it as a reliable method.
Eating Dates
You may have heard that eating dates in late pregnancy can help with labor. A large randomized trial is currently underway to test whether eating three Medjool dates per day starting at 34 weeks increases the chance of spontaneous labor and reduces the need for medical induction. Earlier smaller studies suggested benefits, which is why this larger trial was designed, but we don’t yet have definitive results. At six dates’ worth of calories and fiber per day, there’s little downside to trying, though it won’t produce dramatic overnight changes.
Castor Oil
Castor oil has a long folk reputation as a labor inducer, and a randomized controlled trial published in the American Journal of Obstetrics and Gynecology did find it effective for starting contractions in post-date pregnancies, with no differences in labor complications or outcomes for the baby compared to a control group. That said, castor oil is a powerful laxative. Expect diarrhea, cramping, and possibly nausea. Dehydration from the diarrhea is the main practical risk. If you’re considering it, this is worth a conversation with your provider, especially about timing and dosing.
What Your Body Is Already Doing
Once your mucus plug is gone, your cervix is responding to hormonal shifts that are genuinely preparing you for labor. Prostaglandins are softening and thinning the cervix. Pressure from the baby’s head adds to that process. Your body may also be having irregular contractions you barely notice, gradually doing the work of early dilation.
The frustrating truth is that this phase has no reliable timeline. What you can do is support the process: stay active, stay hydrated, rest when you can (you’ll need the energy), and pay attention to changes. If your mucus plug was clear and you haven’t noticed bloody show yet, you may have more waiting ahead. If you’re seeing blood-tinged discharge, things are progressing.
Signs That Need Attention
Losing the mucus plug on its own isn’t an emergency, but certain symptoms alongside it warrant a call to your provider. A gush or steady trickle of clear fluid suggests your water may have broken, which changes the timeline significantly. Bright red bleeding that soaks a pad (more than a tablespoon or two) is not normal bloody show and needs evaluation. And any noticeable decrease in your baby’s movement, regardless of what else is happening, is always worth reporting promptly.
