Your Pregnancy Week by Week: Weeks 9-12
12 Weeks Pregnant
Baby: All parts of your baby are developing, from tooth buds to toenails. Your baby will keep developing and getting larger and stronger for the rest of your pregnancy. By the end of this week, the chance of miscarriage drops considerably.
Mom-to-be: You'll feel more energetic for the next few weeks. The typical weight gain by now is from 1.5 to 5 pounds. Fathers-to-be might also experience pregnancy symptoms, called couvade, or "hatching," during the third month and at delivery, including nausea, abdominal pain, appetite changes, and weight gain.
Tip of the Week: Try not to fret about stretch marks. Most women get them on the breasts, abdomen, hips, or buttocks sometime during pregnancy. They won't go away, but they usually fade after pregnancy. Despite claims from manufacturers, creams and oils don't minimize them. How much they show depends on your skin's natural elasticity.
What's Happening Inside You?
By the end of the third month, your baby is fully formed, with arms, hands, fingers, feet, and toes. Little hands can open and close. Fingernails and toenails are beginning to develop, and the external ears are formed. Teeth are starting to form. Your baby's reproductive organs also develop, but the baby's sex is difficult to distinguish on ultrasound. The circulatory and urinary systems are working, and the liver produces bile.
