Drag to read about a different week.
No bones about it, you’re baby’s growing a skeleton.
Your baby’s development
The skeleton and intestines are taking shape.
- Your baby grows to about 1 inch—about the length of an olive.
- Beginning with the formation of cartilage, the skeleton begins to harden (ossification).
- Fingers, toes, knees, and elbows develop.
- Nipples and hair follicles form.
- Intestinal system forms, including the pancreas, bile ducts, gallbladder, and anus. Intestines elongate.
- Reproductive organs begin to develop internally.
- Muscles develop and your baby may start to move — you might feel her movements in a few more weeks.
Your nutrition and health
Healthy habits should start now.
Good nutrition includes a healthy diet supplemented with a prenatal multivitamin as prescribed by your doctor. Starting now in your first trimester will help you maintain these habits throughout your pregnancy.
Things to think about now
“Want to hear the heartbeat?” “Uhhhh, yes please.”
- Blood pressure
- Urine for sugar and protein
- Uterus size
- Height of fundus (the top of the uterus)
- Your pregnancy questions or concerns
Your doctor will use a special listening device called a Doppler to project the sounds of your baby's beating heart.
