Your Nutrient of This Week

Say Cheese
Try chewing on a piece of hard cheese to cut down on the chance of pregnancy cavities. Cheese actually reduces the acidity of your mouth and decreases bacteria that can lead to cavities.

During your 31st week of pregnancy, get ready for another prenatal checkup! You probably have a doctor’s appointment this week or very soon, if you’re now seeing your doctor every two to three weeks.

  • By the time you’re 36 weeks pregnant, you’ll probably begin visiting your doctor weekly.
  • These upcoming weekly appointments specifically will check your baby’s progress toward birth.

Your Baby's Development at Week 31

During your 31st week of pregnancy, your baby’s body and brain continue to make the connections that enable her systems to work as a whole. Also when you’re 31 weeks pregnant:

  • Your baby weighs more than 1.5 kg and is 28 cm long from crown to rump, about the length of a bunch of bok choy.
  • Your baby’s reproductive system continues to develop. In boys, testicles are moving from the kidneys through the groin to the scrotum. In girls, her clitoris is visible, but her labia are still growing to cover it.
  • Your baby’s lungs are now more developed but are not completely mature.
  • As trillions of brain connections develop, your baby is already using all five senses.
  • You might notice that your baby has more defined periods of being awake (and active) or asleep.

Your Changing Body at Week 31

When you’re 31 weeks pregnant, your expanding uterus might prompt several additional changes in your body’s normal operation. You might experience some, many, or just a few of the 3rd-trimester pregnancy symptoms.

Your breasts continue to grow larger

  • Your breasts will be 0.5 to 1.5 kg heavier by the end of your pregnancy.
  • Most of this weight is from enlarged milk-producing glands and increased blood.
  • If you already haven’t started to leak colostrum (the first milk for babies who breastfeed), you might begin soon. Breast pads are a discreet and easy way to handle this. However, you might not leak at all before delivery, which is also normal.

Losing Urine When You Laugh is Normal
Ask any pregnant woman and she probably will agree that leaking urine when you cough, sneeze, or laugh can be one of the most annoying symptoms of late pregnancy.

  • Leaking urine is caused by the increased pressure of your growing uterus on your bladder.
  • This problem likely will disappear after your baby is born.
  • Looking to control little leaks?
  • Be sure you empty your bladder completely. Try leaning forward when you’re on the toilet to be sure.
  • Try to go more frequently — as often as every 30 to 60 minutes.
  • Drink at least 8 glasses of fluid a day.
  • Use Kegel exercises that strengthen your pelvic floor.
  • Wear panty liners or pads if needed.

Beauty at its Best
It’s nice to know that your beauty is one of the best benefits of pregnancy:

  • Time for a manicure? During your 31st week of pregnancy, you might have noticed that your fingernails (and toenails) grow at record pace.
  • Head-turning hair! Your hair probably is fuller and in better shape than ever before. You can thank pregnancy hormones, increased circulation, and a pregnancy-prompted change in your hair’s growth cycle.
