You are now 37 weeks pregnant, which is the beginning of week 38.

 

With about three weeks to go, your baby could weigh the average weight of 3.1kg (6 lbs 13 oz) and measure around 48.5 cm long (19 inches) or be smaller or larger. Babies born after 37 weeks are regarded as being born on time or 'at term'.

Your baby now has a good proportion of fat on their body, increasing from only 30 grams at 30 weeks, to around 430 grams at term (approximately 16% of their total body weight). Some physical signs that indicate your baby is born on time is having small pads of breast tissue under their nipples (in both boys and girls) and fingernails reaching the tips of the fingers, often looking manicured!

 

Your baby's overall growth slows down considerably now. They do not grow as much in length and put on approximately 230 grams per week (about an ounce a day). Also, the amount of amniotic fluid around your baby slightly decreases from around 37 weeks.

 

Physical changes

 

Is it water or fluid?

 

Towards the end of pregnancy it is not unusual to produce extra mucus and fluid, which can pool and sometimes trickle away when you get up in the mornings. This can be mistaken for the waters breaking. If you are not sure, go to the toilet and empty your bladder (just to rule out that one as well!) and put on a white pad (to see any colour in the fluid). If fluid continues to come away within the next few hours, it is probably your waters and you need to contact your caregiver or hospital for advice.

Is it a show?

 

During the last couple of weeks of pregnancy, or a few days before labour begins, the mucus show (or plug) may come away as the cervix starts to soften and ripen in preparation for labour. Bear in mind that having a show is not necessary before labour starts and many women pass their show during the birth process. Also, you don't necessarily need to have a show before the waters break.

 

A show is generally very thick and can be clear or grey, pink, brown or blood-stained in colour. It can come away in small dribs and drabs over a few days, perhaps noticed when you wipe yourself with toilet paper. Or it may come out in one large blob, sometimes large enough to fill your hand. Both these are normal. In some cases labour starts within 24 hours or so (but not always!)

 

Labour starting?

 

The question of how labour starts is not yet completely answered, but there are a few schools of thought including:

 

The baby releasing hormones when they realise it is 'time' as the uterine space becomes smaller (with lessening amniotic fluid) and/or the placenta starting to function at less than its peak.

 

• Hormones being released by both mother and baby.

• Hormonal feedback from the placenta.

• A number of the above factors, or something else we haven't discovered yet!

There is some research that supports the theory that an unborn baby's brain sends chemical messages to their mother's body when they are ready to be born. It is still unclear how this actually works, or what triggers the messages to be sent. When labour does begin, the woman releases the hormone oxytocin from her brain, which makes her uterus contract in a rhythmic pattern.

 

Did you know? A woman's uterus is much more sensitive to her natural oxytocin hormone at night. Hence the reason why most labours start once the sun goes down!

 

Emotional reactions 

 

Conflicting emotions are quite normal just before the birth. You may feel relieved because you have had enough of being pregnant and the discomforts that go with it. Or you may feel comfortable with your known state and perhaps unsure about moving forward into the labour and birth (or even parenting). If this is your first baby, the birth can present many questions and concerns about the unknown path that lies ahead.

 

Talk about your feelings with your caregiver and/or partner (if you have one), or with someone else you trust. Sometimes labour does not start until you feel you have resolved your feelings to some degree and are emotionally ready to have your baby.

 

Your new baby 

 

Baby soon after birth

 

The first moments after birth are monumental for your baby. As soon as they leave the womb, they 'switch over' to adjust to life independently from their mother's body.

 

The Apgar score was designed to standardise the way caregivers evaluated the baby's physical well-being at birth. They use five physical signs and give each a possible score of 0, 1 or 2, to reach a total assessment of up to 10 points. The score is usually given when the baby is 1 minute old and again at 5 minutes of age. However, if the baby takes longer to fully breathe and respond the scoring may continue, given again at 7 minutes and possibly also at 10 minutes.

 

Newborn appearance and behaviour

 

Seeing your baby for the first time can bring up many emotions including awe, love and sometimes surprise. Many parents are unprepared for the image of a possibly red, puffy, swollen face of their new creation. If you have had little exposure to newborns, you should prepare yourself for the fact that your baby may initially look very different from the perfect cherub.
