Week 20 Pregnancy:  How big is your baby – fruit?

At this point, your baby weighs around a whopping 9-10 ounces (1)!  He’s measuring 5 2/3 to 6 1/2 inches from crown to rump.  (After week 20, your baby will be measured from crown to heel.)  That puts your little one at about the size of a small banana (4)!

What should my belly look like?

Your uterus is growing, keeping pace with baby’s rapid growth.  Now the top of the uterus is about even with your belly button, and your starting midway through your second trimester appointments, provider will be measuring the growth of your abdomen using a measuring tape.  This is called measuring the fundal height, and it helps your doctor check that your baby is growing as expected. Typically it’s done from the pubic symphysis, an area near the pubic bone, up to your naval.  Right now, this measurement will likely be somewhere around 8 inches long.  Expect the distance to grow almost 1/2 inch each week!

Week 20 Pregnancy:  Baby’s development

Your baby is continuing to grow and develop, and is doing some pretty amazing things this week (3)!

  • Eyebrows and eyelashes are beginning to form
  • Nails are present on both fingers and toes
  • Lanugo (a fine, downy hair that typically falls offer before birth) now covers your baby’s body
  • Vernix ( a white, cheesy substance that acts as a skin barrier) is starting to form on your baby’s skin
  • Baby’s limbs are well-formed

Week 20 Pregnancy:  Symptoms


If you haven’t already, you’ll soon begin to feel your baby move!  This is known as quickening.  Pay attention to a gentle, fluttery feeling in your uterus.  It’s almost like a little butterfly is flapping around in there!  (Honestly, while this doesn’t sound cute, it may feel like you have gas.) You may have noticed this movement as early as 16 weeks, but most moms are able to recognize baby’s movement by around week 20.

Stuffy Nose & Nosebleeds

Elevated estrogen levels during pregnancy cause an increase of blood flow to all of your mucous membranes.  This results in swollen mucosal tissue, and commonly nasal congestion. Additionally, always having to blow that annoying stuffy nose sets pregnant moms up for the occasional nosebleed.

Unfortunately, antihistamines and decongestants are typically discouraged during pregnancy.  Ask your provider about the use of a saline spray.  Running a cool-air vaporizer during the night may bring relief…or it may not.  Either way, expect the congestion to stick around until baby is born.
