You are officially 'late term'. While waiting this long is incredibly frustrating, it is quite common, especially for first-time mothers. Your baby is completely developed and continues to gain a small amount of weight. However, because the placenta has a limited lifespan, your doctor is monitoring you closely to decide if it's time to step in and evict the baby.
🍼 What's Happening With Your Baby
Now the size of a watermelon, your baby's fingernails and toenails are very long and may need clipping immediately after birth.
The vernix (the waxy coating) and lanugo (fine hair) have almost completely disappeared, meaning the baby's skin may be slightly dry or peeling at birth due to extended exposure to the amniotic fluid.
The endocrine system is fully mature, producing the complex cocktail of hormones needed to initiate the labor process.
🤰 What You're Feeling This Week
The physical discomfort is absolute. The sheer weight of the uterus makes moving, sitting, and sleeping a monumental effort.
You will undergo increased monitoring, including Non-Stress Tests (NSTs) to check the baby's heart rate, and Biophysical Profiles (BPPs) via ultrasound to check the amniotic fluid levels and fetal breathing.
Your doctor will likely schedule an induction if labor does not begin spontaneously. This may involve medications like Pitocin to stimulate contractions or a balloon catheter to manually dilate the cervix.
The Aging Placenta
The placenta was designed to last about 40 weeks. As you pass week 41, it begins to calcify and become less efficient at transferring oxygen and nutrients, which is why medical induction becomes necessary.
✅ What To Do This Week
-
✦
Prepare for induction — Ask your doctor exactly what the induction process will involve. Will they use a cervical ripening agent overnight? Will they break your water manually? Knowing the steps reduces anxiety.
-
✦
Rest aggressively — An induced labor can sometimes take longer than spontaneous labor. Do not waste your energy pacing the floors. Rest your body for the marathon ahead.
-
⚠️
Go to triage for any red flags — Decreased fetal movement, bright red bleeding, or your water breaking (especially if the fluid is green or brown, indicating meconium) require immediate medical attention.
"You are so tired, so stretched, so ready. The baby is safe, but the lease is up. The end is no longer approaching; it is here."
