Your partner can't see much evidence of your pregnancy yet (other than a tiny baby bump and the flu-like symptoms you've been feeling), but you can still map your baby's progress together. Ask him to go with you to your prenatal visits. It's a great way to get questions answered, to bond and to understand more about baby's development.
By Week 10, your baby has moved past the embryonic stage and is now officially a fetus. She's about the size of a lime and is less at risk for physical birth defects. She has fingers and toes to wiggle and has formed all of her internal organs. Vital organs, including the liver, kidneys, intestines and brain, kick into action. Your baby's brain, for example, is producing 250,000 new brain cells every minute. It's no wonder her head is about half her total length!
If you were to look closely at your baby, you'd notice she doesn't look like a tadpole anymore. Her embryonic tail, located at the bottom of the spinal cord, has disappeared and her rapidly developing spinal nerves have become visible. Her eye color has been determined and the irises are forming. The eyelids are fused shut and will not open again until Week 25.
