1. Fetal development at 13 weeks
The development of the fetus at 13 weeks (equivalent to 11 weeks after fertilization) is characterized by the phenomenon that the fetus begins to drink amniotic fluid and excrete urine into the amniotic cavity, and again to drink, forming a cycle.
The bones of the fetus begin to strengthen, especially the skull and long bones. The fetus can move its arms and legs randomly, and can especially put its thumb in its mouth (a habit common in babies after birth). Your baby's skin is still thin and easy to see through, but it will soon thicken. During this 13th week, your baby's vocal cords will develop.
Average fetal length and weight at 13 weeks are 6.7cm (2.6inch) and 73g (2.5 ounces) respectively.
