Fetal Development Pregnancy week 4

So what's going on in your womb this week? Your embryo may be minuscule, but trust us: Super-important developments are already under way. This week the embryo splits into two parts. One half will become the placenta, a special tissue that delivers must-have nutrients and oxygen to your baby throughout your entire pregnancy. In the other half, the embryo itself continues to grow, and a sheet of cells has just begun to create the neural tube, where your baby's brain, spinal cord and backbone will ultimately form. 4 of 42

This week, your baby's ticker will start beating for the first time! ( Neither you nor your doctor can hear it yet, but it may be possible to see the movement on an ultrasound .)
