Updated on

  • Baby size 1.3 cm
  • About the size of a blueberry

In the seventh week of pregnancy, your baby continues to grow at an accelerated rate. The embryo has increased in size and now has more defined structures such as developing eyes and ears, as well as limb buds that will become arms and legs. The nostrils and lenses of the eyes are also forming. This is a crucial time in development where facial features and major body structures begin to take shape.
