Pregnancy Week 7
During week 7, your baby's face and brain continue to develop.
Eye lenses and nostrils begin to form.
The arm buds that developed last week take on a paddle shape.
The umbilical cord that will provide your baby with oxygen and nourishment throughout your pregnancy, forms.
The lungs and digestive tract also continue to form.
By the end of this week, your baby will be about 4/16 to 5/16 inches or 7 to 9 millimeters in length from crown to rump.
Due to an increase in hormones, your face may start to break out.
On the flip side, some women have a clearer complexion during pregnancy.
