Pregnancy week 37
This week your baby is about the size of a bunch of Swiss chard — around 48.6 cm and 2859 g.
Your baby this week
Your baby is now about as long as a bunch of Swiss chard and is considered early full term, meaning the organs are largely ready for life outside the womb. Your baby practices breathing by drawing amniotic fluid in and out, and the grip grows stronger. Fat keeps being stored to provide warmth and energy after birth. Although most growth is complete, the brain and lungs keep maturing in these final days, so every safe week inside is beneficial.
Your body this week
You may feel a mix of excitement and nervousness as the date nears, along with heaviness in the pelvis and frequent trips to the bathroom. It is common to notice more vaginal discharge or the passing of the mucus plug, natural signs that your body is getting ready. If you notice your waters breaking or regular contractions that grow stronger and closer together, contact your care team.
Tips for this week
Make sure you know the route to the hospital, who will accompany you, and that your doctor's number is within reach. Rest and recharge your energy, since labor calls for strength and patience. Practice relaxation and breathing exercises, and remember your body is made for this moment, so lean on your loved ones for support.
