Understanding Week 40 of Pregnancy
Congratulations on reaching the 40-week mark! As you prepare to welcome your little one, this guide will help you navigate this pivotal moment in your pregnancy, discussing your body’s changes, your baby’s development, and what to expect as labor approaches.
Your Body at 40 Weeks
As you enter week 40, be prepared for labor to begin at any time. While the third trimester has likely been a journey filled with excitement, you are undeniably ready to meet your new arrival. It’s important to note that, despite common portrayals in media, only about 15 percent of women experience their water breaking before labor starts.
When the water breaks—medically referred to as premature rupture of membranes (PROM)—it can be confusing to differentiate between amniotic fluid and urine. The sensation may feel like either a trickle or a gush, and the fluid itself is typically clear or pale yellow with no odor. If you suspect your water has broken, keep track of the time and start monitoring contractions.
Contractions are a clear sign that labor is imminent. Initially, they may last 30 to 60 seconds, spaced five to 20 minutes apart. As labor progresses and contractions intensify—lasting 45 to 60 seconds with breaks of three to five minutes—it’s time to head to the hospital, as your baby is preparing to make their grand entrance.
Your Baby’s Development at 40 Weeks
At this stage, your baby is roughly the size of a turducken, weighing between six and nine pounds and measuring 19 to 22 inches long. Variations in size are normal, so don’t worry if your baby is a bit smaller or larger. It’s quite cramped in your uterus now, and you may only feel about ten movements per hour as they await their debut.
Most of your baby’s bones have solidified by this point, with the exception of the skull. The bones in the skull remain soft and flexible to facilitate passage through the birth canal, and will continue to harden over the next several months. If you opt for a vaginal birth, your newborn may have a slightly cone-shaped head and some bruising, but rest assured, they will be perfectly adorable.
Symptoms and Health Considerations at Week 40
As labor approaches, your body undergoes cervical dilation and effacement. These processes prepare your cervix for delivery, although they often occur unnoticed until you are well into labor.
It’s essential to remain flexible as you near your delivery date. While you may have envisioned a specific birth plan, remember that not everything will be under your control. Embrace the journey, and know that you are ready to meet your baby.
