It can be unsettling for expectant parents when contractions begin and then unexpectedly cease. This experience is common and can lead to confusion about whether labor is truly starting or if something is amiss. Understanding the various reasons why contractions may slow or stop can help alleviate concerns and provide clarity during this stage of pregnancy.
Understanding Different Contractions
Pregnant individuals experience various types of uterine contractions. Braxton Hicks contractions, or practice contractions, are typically irregular in timing and intensity. They do not increase in strength over time and usually do not cause changes to the cervix. These contractions frequently subside with rest, hydration, or a change in position, which explains why they often stop.
Prodromal labor represents an intermediate phase, sometimes called “false labor” or “prelabor.” Contractions during this stage can be more organized and noticeable than Braxton Hicks, potentially occurring with some regularity. Similar to Braxton Hicks, these contractions do not lead to active cervical dilation and effacement. They often fade or stop, rather than intensifying into established labor.
True labor contractions, in contrast, follow a more predictable pattern. They become progressively stronger, longer, and closer together. These contractions thin out and open the cervix. Unlike the other types, true labor contractions do not stop with changes in activity or rest.
Reasons True Labor May Slow or Stop
Several factors can cause true labor contractions to slow or stop. Physical and mental exhaustion can impact the uterus’s ability to contract effectively. Fatigue can lead to less efficient uterine activity. Rest can help re-energize the body.
Dehydration is another common reason for contractions to become less effective or cease. The uterus requires sufficient fluid balance to function optimally. Insufficient hydration can lead to weaker, less coordinated contractions. Consuming fluids like water or clear broths helps maintain hydration.
Emotional factors, such as stress, fear, or anxiety, can also play a role in stalled labor. Stress hormones, like adrenaline, can inhibit oxytocin production, which is responsible for uterine contractions. Creating a calm and supportive environment can help counteract these effects.
An unfavorable fetal position can hinder the natural progression of labor. If the baby is not optimally positioned, contractions may become less effective in dilating the cervix. This can slow labor progress as the body adjusts or the baby repositions.
Uterine dysfunction, also known as uterine inertia, means contractions are not strong or coordinated enough to cause progressive cervical changes. This can be a primary condition or develop during labor.
Certain medications during labor, particularly pain relief options like epidurals, can temporarily slow contraction frequency or intensity. Healthcare providers monitor this effect closely. Labor also includes periods where cervical dilation might slow before resuming its progression.
When to Contact Your Healthcare Provider
Specific warning signs warrant immediate attention: a sudden gush or trickle of fluid, especially if discolored green, brown, or foul-smelling, which could indicate ruptured membranes. Significant vaginal bleeding heavier than spotting, or a noticeable decrease in fetal movement, also warrant prompt medical advice. Other concerning symptoms include fever or severe, unrelenting abdominal pain.
If previously strong, regular contractions indicative of true labor completely cease, contact a healthcare provider. They can assess the situation and determine if intervention is necessary. The context of the contractions helps guide this decision.
Contact a healthcare provider if there is any uncertainty, persistent worry, or if contractions that felt like true labor suddenly stop. While Braxton Hicks or prodromal labor often resolve with rest or hydration, call if concerns persist.
