33 Weeks- Development

Your Baby This Coming Week

Your baby weighs almost 5 lbs (2250 g) and is 12.8 inches (32cm) from crown to rump and about 19.8 inches (44cm) long.
If your baby were born now, she would be considered "pre-term" rather than premature. This distinction is based on fetal maturity, particularly the maturity of the fetal lungs. A pre-term baby, unlike a premature baby, is likely to have well-developed lungs and is less likely to need intensive care.
Your baby is surrounded by a red glow when sunlight shines on your belly and may be aware of this as she is able to differentiate between light and dark.
Your baby's hair is getting thicker, though it may be a different color when she is older.
She is currently shedding her lanugo, the fine downy hair that previously covered her body.
More vernix, the waxy coating that protects your baby's skin while submerged in amniotic fluid, is building up.
Your baby's adrenal glands are producing more steroid hormone, the androgen-like hormone that indirectly aids your milk production. Your baby is currently producing ten times more of this hormone than a normal adult and the adrenal glands are currently the same size as those of an adolescent. They will shrink after birth.
Your baby is laying down bone. To do this, she will draw calcium from you.
Your baby has taste buds and it has been suggested that she can taste and develop tastes for flavors found in the amniotic fluid, particularly flavors that you eat on a regular basis.

Your Body This Coming Week

Your baby is beginning to drop in your pelvis and you may have noticed that the shape of your abdomen has changed because of this. This may also cause increased pressure in your pelvic region.
While Braxton Hicks contractions are probably becoming more regular, you may also experience false labor. This is different from Braxton Hicks contractions because false labor, unlike Braxton Hicks, can be very painful. These contractions are irregular and usually last under 45 seconds and are not sustained. If you are unsure if you are experiencing false labor, you should contact your care provider.
If your water breaks, you should contact your doctor immediately.
You may have bloody show that occurs as the cervix stretches and dilates, especially right after a vaginal exam. You may also pass a mucus plug. Neither bloody show or passing the mucus plug necessarily indicates that labor will commence right away, but it will not be far away.
