As pregnancy progresses into the 30th week, many women experience mild abdominal contractions, which may confuse their nature: are they a sign that labor is approaching, or simply temporary contractions that do not require concern, known as Braxton Hicks contractions?
In general, these contractions are temporary, and it is important to note the differences between these contractions and labor contractions, understand their causes and how they can be properly managed.
What Are Braxton Hicks Contractions?
Braxton Hicks are weak, irregular uterine contractions. You may feel a slight muscle spasm or pressure without discomfort or any effect on breathing or movement.
They normally begin in the second to third trimesters and increase steadily in strength and intensity as the fetus and uterus expand, pressing upon the other organs.
These contractions play an important role in strengthening and increasing the flexibility of the uterine muscles, preparing them for labor at the proper time.
The difference between Braxton Hicks Contractions and real labor pains
It is essential to distinguish between Braxton Hicks contractions and the true labor contractions, so that make the right decision at the right time without unnecessary stress or anxiety.
Here are the major differences between true and false contractions:
| Braxton Hicks Contractions | Labor pains | |
| Timing | Irregular, occurring at varying intervals | Regular, stronger, and closer together |
| Intensity | The pain is minimal to moderate, not more than aching. | Painful, such as menstrual cramps with pelvic pressure |
| symptoms | Without annoying symptoms | Bleeding, fluid leakage, or heavy pressure |
What causes Braxton Hicks contractions?
Braxton Hicks contractions arise from several physical and environmental factors, which include:
- The uterine stretching as the baby grows would sometimes trigger contractions in the muscles.
- Excessive movement, prolonged standing or physical exertion can increase pressure on the uterus.
- Dehydration or loss of fluids reduces muscle efficiency and increases the chance of contractions.
- A full bladder, which temporarily presses on the uterus and stimulates contractions.
- Sexual intercourse may stimulate the muscles of the uterus and cause contractions.
- Hormonal changes in pregnancy, especially increased oxytocin levels, may stimulate muscle contractions.
How Does the Uterus Change During Pregnancy?
The uterus is one of the most flexible body parts, so it has the capability of stretching along with the baby’s growth in the womb. Braxton Hicks contractions prepare the uterine walls for the actual labor contractions.
When to Call Your Doctor Immediately?
Although Braxton Hicks contractions are generally normal and harmless to the mother or baby, several warning signs require urgent medical attention, including:
- Increased intensity, with regular contractions every 10 minutes or less.
- Vaginal bleeding or water leaks.
- Abdominal or lower back pain.
- Associated symptoms such as lightheadedness and difficulty breathing.
If the symptoms have happened before the 37th week of the pregnancy, they can signal pre-term labor or require further medical evaluation.
Helpful Tips to Relieve or Stop Contractions
Although these contractions may not be prevented, the following tips can help decrease their frequency or occurrence:
- Lying down on the left side to increase blood flow and reduce pressure in the uterine area, and taking rests when possible.
- Drinking water to stay hydrated and prevent muscle contractions.
- Avoiding overexertion, prolonged standing, or walking without resting.
- Practicing deep breathing, prenatal yoga or meditation to relax and relieve muscle tension.
- Observing the strength and rate of the contractions to ascertain if it is normal or requires medical attention.
- Avoiding stress or anxiety that may impact the muscles of the uterus and stimulate uterine contractions.
Effect of Physical Exercise on Braxton Hicks Contractions
Moderately engaging in physical activity, such as walking or light prenatal exercises, an be a very effective way to enhance blood circulation and strengthen pelvic muscles, to minimize the frequency of Braxton-Hicks while preparing for labor.
Active movement can also help in relieving tension, improving respiration, lessening the contractions’ intensity, and enhancing the endurance of the mother.
Too much exercise may increase the intensity of contractions and negatively affect pregnancy. Thus, balance activity and rest, and stop immediately if strong or unusual contractions occur.
Hormonal Changes and Their Role in Inducing Contractions
The levels of hormones change during pregnancy. For example, the oxytocin hormone rises significantly in the 3rd trimester of pregnancy, which causes uterine contraction and preparing the uterus for childbirth.
These hormones, along with progesterone, regulate uterine muscle activity and increase its sensitivity, causing occasional mild contractions.
Are Braxton Hicks Contractions Affecting Baby Movement?
These contractions do not have any effect on the movement of the fetus, which is normally occurring. However, if an unusual change in the baby’s movement has occurred, it is recommended to contact a doctor.
In conclusion…
Only a few weeks remain to meet your baby. During this time, your body begins preparing for delivery through Braxton Hicks contractions, which are natural training for your uterus before actual labor. Stay calm and follow the tips that help relieve them. However, do not hesitate to contact your doctor if you notice any unusual changes.
