39 weeks pregnant
Your Developing Baby-
• When you’re 39 weeks pregnant, your infant’s weight is around 7.25 pounds (3288gm) and length is 20 inches (51cm).
• Now, your baby’s lanugo have mostly disappeared. If not, then definitely they shed off within 1 week or two.
• His lungs are maturing and surfactant production is increasing and fully prepared to take on the outside world.
• Now space is very limited for your baby in your tummy. He has a full grown baby, when you’re 39 weeks pregnant.
• The hair on your baby’s head may now be thick, and his fingernails extend beyond his fingertips.
• Your baby’s skull bones are not yet fused, which allows them to overlap as he passes through the birth canal during labor. This is the reason your baby’s head may look cone-shaped after birth.
• He is continuing to store more fat.
• In addition to normal fat, when you’re 39 weeks pregnant, baby start to accumulating a special “brown” fat on the nape of his neck, between his shoulders and around organs. Brown fat cells are important for thermogenesis (generating heat) during his first weeks.
Your Changing Body-
It’s all about watching and waiting now, as your baby could arrive any day. And if the week passes and there’s still no baby? Don’t worry – babies have a habit of not arriving on their scheduled due date. Most doctors wait another two weeks before considering a pregnancy overdue.
Your body has been supplying the baby with antibodies through the placenta that will help the baby’s immune system fight infection for the first 6-12 months of life.
Early Sign of labor-
Braxton Hicks contractions may become more pronounced. Also called “false labor,” these contractions may be as painful and strong as true labor contractions, but do not become regular and do not increase in frequency as true contractions do.
Another sign of labor, the rupture of your amniotic sac, could happen any day now. When their water breaks, some women experience a large gush of water and some feel a steady trickle. Many women don’t experience their water breaking until they’re well into labor.
If you started feeling these signs, contact your health provider now.
