Fetal Development: Week 14

Week 14 of your Pregnancy

Baby now weighs about 1½ ounces or 45 grams and is around 3½ inches or 9 cm long (crown to rump), about the size of your fist.

Your baby’s body is now starting to catch up with its head.

Pregnancy Week 14Ultra-fine, soft hair called lanugo is starting to cover baby’s soft translucent skin which will protect baby’s skin while in the amniotic fluid.

Your baby can now squint, frown, grimace, pee, and suck his/her thumb!

The genitals are fully developed but may still be difficult to detect on ultrasound.

Baby’s bones are also getting harder and stronger.

What to Expect

2nd Trimester screening tests are usually offered and scheduled between weeks 15 to 20 to estimate the risks for three conditions: 

  • Open neural tube defect (spina bifida),
  • Down syndrome (Trisomy 21), and
  • Trisomy 18.

If your doctor recommends a screening test, be sure to learn about the risks and benefits.

Tips for Week 14

For many women, the second trimester is the time of their pregnancy when they feel best.

Now that the nausea has settled and your energy levels are back, it is time to get out and about walking, exercising, shopping, taking a vacation or just doing something you enjoy outdoors.

Start looking at options for a pediatrician – begin interviewing possible choices for your baby.

Now would also be a great time to start doing your pelvic floor exercises.
