It's starting to feel a little more real now, isn't it?

  • The bones of the face are forming right now. The eyelids are still shut and won't open for a long time.
  • The earbuds on the sides of your baby's head will like ears as he develops.
  • Your baby's head accounts for one-third of his or her overall length, but the body straightens out as it grows.
  • The fingers and toes are starting to separate. Fingernails can be seen.

How big is your baby?

Your Body3,4

  • As your waist thickens, you may believe your 'bump' is quite apparent, yet most people will be completely unaware that you're expecting a baby.3
  • As you bulge out slightly, your muscles and ligaments will stretch, may cause pains in the area around your stomach.3
  • Right now, your body is pumping up to 50% more blood than it normally would. Blood nourishes your womb, but it can also make you feel hot, sweaty, and disoriented. That's how your baby is asking you to relax and drink some water!3
