Your baby has grown to the size of an apple and weighs about 2 1/2 ounces. (Length: 4 inches, head to bottom.)

He's busy inhaling and exhaling amniotic fluid, which will help the air sacs in his lungs develop. Sweat glands are appearing, and although his eyelids are fused shut, he can sense light. If you were to shine a flashlight at your tummy, he'd most likely move away from the beam.

Our next doctor's appointment is next Thursday at 15 weeks and 6 days. I'll let you know how it goes!
