Week 29 pregnancy 3D weight & symptoms

Week 29 of your pregnancy is finally here, and you’re now 27 weeks from conception.  Let’s learn all about 3D ultrasounds, weight gain, and pregnancy symptoms in week 29!

Week 29 Pregnancy:  Weight

By week 29, your baby weighs about 2 1/2 pounds.  She’s getting taller, too!  She now measures about 15 1/4 inches from crown to heel.  Now that your baby has developed all of her major organs, the focus shifts to gaining weight.  And your little one will start gaining quickly fro!  During these last 2 1/2 months of your pregnancy, half of the baby’s weight at birth will be added.  Be sure that you’re eating a nutritious diet and supplementing with a multivitamin to help complete her growth (3).

Your uterus rests around 3 1/2 to 4 inches above your belly button.  It measures a distance of about 11 1/2 inches from your pubic symphysis to your naval.  By week this week, you’ve probably gained somewhere between 19 and 25 pounds (2).

Week 29 Pregnancy:  3D Ultrasounds

3-Dimensional (3D) ultrasounds create images of your baby that look more like a photograph.  While the procedure is similar to a normal 2D ultrasound, the main difference is that computer software turns the picture into a 3D image.

When medically necessary, 3D ultrasounds can be a valuable diagnostic tool.  A 3D image can help assess babies with facial problems, hand and foot problems, spinal problems, and neural tube defects (2).  Other helpful uses of 3D ultrasounds include measuring the volume of amniotic fluid and observing subtle differences in cleft-lip and cleft-palate problems (2).

Some non-medical facilities, like shopping malls, offer 3D keepsake ultrasounds.  While there are no known risks of ultrasounds during pregnancy, it should be use cautiously and only when necessary.  The American College of Obstetricians and Gynecologists discourages the non-medical use of ultrasound for entertainment, keepsakes, or finding out baby’s gender (3,5).

Week 29 Pregnancy:  Symptoms


Constipation is a common discomfort during pregnancy.  Some reasons why you might be experiencing more constipation include:

  • Increased levels of progesterone, which cause the bowels to be sluggish
  • Pressure of the growing uterus on the intestines
  • Iron supplements
  • Possible lack of exercise

Fortunately, there are effective self-care measures to help combat the constipation blues.  Helpful suggestions include:

  • Drink more water (10-12 cups daily)
  • Increase the fiber in your diet through fruits, vegetables, and whole grains
  • Exercise regularly.  Exercise helps speed up your bowels by moving food through them more quickly.  (Always consult with your health care provider before starting a new exercise routine!)
  • Use a stool softener as recommended by your doctor or midwife (1)

Begin Kick Counts

Starting at around week 28 or 29, your doctor or midwife might encourage you to track your baby’s movement.  This is known as fetal kick counting.  Most babies have several active, wakeful periods in the day.  They also have periods when they sleep.  Your goal is to record your baby’s movements each day at roughly the same time when he’s normally active.

One way to record this is the count-to-ten method.  Find a comfortable position and time how long it takes your baby to move ten times.  (Ask your provider for specific instructions.)  Over time, you’ll develop a good sense of how active your little one is.  Then, if your baby becomes noticeably less active, you’ll know to reach out to your doctor to assess baby’s well-being (4).
