-At week 9, your baby has graduated from embryo
to
fetus.
She is nearly an inch long and looks more
like a baby for digestive tract and reproductive
organs are
formed, but it's still too early for even
for a
skilled technician to tell whether you're
having a boy or
a girl.
This week, your baby may start hiccoughing
one
of the earliest movements that fetus makes.
Soon, you'll feel
the tail jerks that come with each hiccough.
By week
10, he's about the size of a grape and can
stretch his spine.
Because his head so large, the stretch
causes the whole body to turn around.
The eyes and
eyelids are more developed, and eyebrows have
started to grow.
It looks like your baby is sleeping, but a
lot
is happening this week.
The outer part of the ear
is developing and tooth buds are forming.
His brain is
producing almost 250,000 per minute.
His liver, instead of the
yolk sac is now producing blood cells.
His kidneys are
producing urine and releasing it into the
amniotic fluid.
The
skin consists of many layers and isn't transparent
anymore.
Male
babies start producing the sex hormone testosterone.
By the end
of 10 weeks, your baby has more than 90% of
the anatomic structures present in adults.
You baby is about
2 inches long by week 11.
From now through week
20 of your pregnancy, she will increase 30
fold in
wight and will triple in length.
A skilled technician might
be able to tell at this point whether you're
having
a boy or girl, but most of the time, a
baby sex can't be detected until 15 or 16
weeks.
You can't feel it, but your baby is experiencing
muscle
twitches as she grows.
Your baby is almost 3 inches
long by week 12 with fingernails, toenails,
and bones forming.
A fine layer of hair covers most of his body.
There are about 3 tablespoons of amniotic
fluid surrounding the
fetus and he may began to swallow small amounts
of
it.
