12 Weeks

12 weeks
Info taken from
What your baby's up to by now, nearly all of your baby's organs, structures and systems are fully formed. Your baby's heart begins pumping several quarts of blood through your baby's body every day. While your baby's brain is not the same size it will be at birth, it does have the same structure. Your baby's fingers and toes have separated and his hair and nails continue to grow. Your baby is approximately 2.5 - 3.5 inches and weighs about 12 - 14 grams.
Also, the external genitals can now show definite signs of male and female sex, however it will probably still be impossible to tell by ultrasound whether you are having a boy or a girl. Where there was only reflex movement before, your baby now moves spontaneously and at random, but he is still too small for you to feel him. With the use of a Doppler, you might be able to hear your baby's heart beat at your next doctor's office visit. It will sound very fast and will sound similar to that of a running horse.
