Being 38 weeks pregnant marks a significant milestone, bringing you very close to meeting your baby. This period is characterized by anticipation, as your body and baby continue their final preparations for birth. Understanding what to expect during this stage can help you navigate the remaining days with confidence and a sense of readiness.
Your Body’s Journey
At 38 weeks, your body undergoes several changes as it prepares for labor and delivery. You might experience increased pressure in your pelvis as your baby descends lower, a process sometimes called “lightening.” This shift can relieve pressure on your lungs, making breathing easier. However, it may also intensify pelvic discomfort and frequent urination.
Braxton Hicks contractions, often described as “practice contractions,” may become more frequent and intense during this time. These contractions are typically irregular, do not consistently increase in strength or frequency, and may ease with changes in position or activity. They help prepare your uterus and cervix, potentially contributing to cervical thinning (effacement) and early dilation.
Vaginal discharge can also change at 38 weeks, often increasing in volume. You might notice the loss of your mucus plug, which is a thick, jelly-like discharge that sealed your cervix during pregnancy. This can appear clear, white, yellow, green, brown, or be tinged with pink or red blood, also known as “bloody show.” While its loss indicates cervical changes, it does not necessarily mean labor is imminent, as it can occur days or weeks before true labor.
Continued fatigue, insomnia, and general discomfort are common as your body carries the full weight of pregnancy. Backache, swelling in the feet and ankles, and heartburn can persist or worsen. These sensations are a normal part of the body’s final stretch towards childbirth.
Your Baby’s Final Preparations
By 38 weeks, your baby is considered “early term,” nearing the “full term” classification which officially begins at 39 weeks. At this stage, babies typically weigh around 6.8 to 7.1 pounds (approximately 3.1 to 3.2 kg) and measure about 19.4 to 19.6 inches (around 49 to 50 cm) from head to heel. While their weight gain may slow, they continue to accumulate fat layers, which are important for temperature regulation after birth.
All of your baby’s organ systems are developed, with the lungs and brain continuing to mature significantly in these final weeks. The fine, downy hair called lanugo, which covered their body, has mostly shed, though some babies may still have patches at birth. A protective, creamy substance called vernix caseosa still covers their skin, shielding it from the amniotic fluid.
Your baby’s intestines are now filled with meconium, a dark green, tar-like substance that will be their first bowel movement after birth. While movement might feel less expansive due to limited space, it is still important to monitor fetal activity regularly. A noticeable decrease in movement should prompt immediate contact with your healthcare provider.
Recognizing Labor’s Onset
True labor contractions follow a regular pattern, become progressively stronger and longer, and do not subside with rest or changes in activity. They often start in the lower back and wrap around to the abdomen, lasting between 30 to 70 seconds and becoming more frequent over time.
The rupture of membranes, commonly known as your “water breaking,” is a definitive sign of labor. This can manifest as a sudden gush or a slow trickle of clear or pale yellow fluid. If your water breaks, especially if the fluid is green or brown, indicating the presence of meconium, you should contact your healthcare provider immediately.
Loss of the mucus plug or “bloody show” signifies cervical changes, which can precede labor by days or weeks. Other subtle indications that labor could be approaching include increased back pain, cramps, diarrhea, and a surge of energy often referred to as the “nesting instinct.” It is important to contact your doctor or midwife if you experience regular, strong contractions, fluid rupture, significant vaginal bleeding, decreased fetal movement, or concerning symptoms like severe headaches or blurred vision.
Practical Preparations for Birth
As your due date approaches, several practical steps can help you feel more prepared for your baby’s arrival. Finalizing your hospital bag for yourself and your baby is advisable by 36-37 weeks, ensuring essentials are easily accessible. This includes comfortable clothing, toiletries, and any personal items that might enhance your comfort during labor and postpartum.
If you have a birth plan, reviewing it with your partner and care team ensures everyone is aware of your preferences. Installing and having your baby’s car seat inspected is a safety measure before leaving the hospital.
Preparing the nursery and gathering essential baby supplies, such as diapers and clothing, can also alleviate stress. Arranging for support after delivery, like freezer-friendly meals or help with household tasks, allows you to focus on recovery and bonding with your newborn. Confirming the quickest route to your hospital or birthing center ensures a smooth journey when labor begins.
Emotional Landscape and Support
The final weeks of pregnancy can bring a wide range of emotional experiences. Many individuals report feeling a mix of excitement, anticipation, impatience, and anxiety about labor, delivery, and the responsibilities of parenthood. These fluctuations are a normal response to the significant life change ahead.
Open communication with your partner and support system can be beneficial during this time. Sharing your feelings and concerns can help alleviate emotional burdens. Prioritizing self-care practices, such as adequate rest, gentle relaxation techniques, and light activity like walking, can also support mental well-being.
If anxiety or feelings of sadness become overwhelming, or if you suspect symptoms of depression, reaching out to your healthcare provider for professional support is a positive step. Mental health support is an important aspect of preparing for childbirth and postpartum recovery.
