Your pregnancy at 39 weeks
What's happening with mum
Mum is waiting patiently for a sign or signs that labour is beginning. One of these signs is what they call "the water's breaking". This is a term used for the rupture of the fluid-filled membranous sac called the amniotic sac which has enclosed your baby in the womb.
Although in movies this tends to happen in a gush, it is also possible for your to slowly leak fluid as their may be only a small hole in the sac or your baby's head plugging your cervix allows only a trickle to leak out a time.
Unlike urine, amniotic fluid is usually colorless and odorless and has a sweeter smell, may contain some bloody flecks or whitish flecks of mucus.
All women are different and while some women find their water's break before labour, most of the time this happens when contractions have already begun.
What's happening with baby
Babies on average at week 39 weigh 7 to 8lbs and are 19 inches long. Although there are few physical changes from last week, except fat deposit, internal changes continue in ernest. Brain continues to develop, organs and systems practice and prepare for after delivery.
Your baby's skin should now be pink and smooth as the lanugo will be shed most likely before birth, although some babies retain a small amount and the vernix, the soft white cheese like substance will also be shed.
If you are 39 pregnant your due date is from Sunday, 25 March 2018 through Saturday, 31 March 2018.
