Week 10: Pregnancy Week By Week 3D Ultrasound Images

Week 10 marks an important milestone for your little one: The end of this week is the end of your baby’s embryonic period and the start of the fetal period. This is when the embryo begins resembling a little human. All of her vital organs have formed and are starting to work together and she has begun breathing amniotic fluid.

At this point, your baby’s head will be over half of her total length as the head slowly becomes more rounded as well. The average size of a baby at this stage is 1.06-1.38 inches or 2.7-3.5 cm crown to rump length (CRL). Your baby should weight roughly 4 grams (.14 ounces). Tiny toes are forming and the eyes are largely open but will begin to fuse shut and will remain shut until weeks 25-27.

External ears and an upper lip are beginning to form and tooth buds are forming inside her mouth. The tail has also completely disappeared by this point.
