 | Your third trimester will mark fun milestones such as a baby shower and
preparing the nursery. During this trimester you may also feel
uncomfortable as your body prepares for labour and child birth. Try to
get as much rest as you can in your 3rd trimester. |
What’s happening to your baby? Weeks 29-32
She fully formed
now. Her lungs continue to mature. Her brain and nervous system are
developed. She responds to light and dark. She can differentiate
between sweet and sour tastes. By week 32 she will measure about 39cm
in length and her weight will be 3lb 12oz. Her fat stores continue to
increase. Weeks 33-36
Her movements decrease as she has less
space to move around. She starts to lose her covering of lanugo. She
now urinates and her intestine has filled with meconium (baby’s first
bowel movement). She may turn so that her head is facing downwards. Her
head can engage into your pelvis around this period of time. At week 36
she weighs in at 5lb 9oz and measures about 44cm in length. Weeks 37-40
If
she is born at this stage she will be classed as full term. The vernix
that protects her skin begins to disappear. She has now fully matured
and is ready to be born. The average birth weight is 7lb 71/2oz. She
will be about 50cm long. She can arrive anything up to 2 weeks after
her due date. Don’t worry if she is late, it will all be worth it!
What’s happening to your body? Weeks 29-32
Your
weight continues to increase; you will probably feel that you can’t get
much bigger but you will (sorry). You may find that you start to
experience Braxton Hicks contractions, which are tightenings across
your tummy. These are normal but if you are worried that labour may be
starting contact your midwife. You will probably feel hot most of the
time.
To alleviate back pain, stand or sit up straight. When
lying down, lie on your side with a pillow between your knees; avoid
lying on your back. Weeks 33-36
Your breasts are filling with
colostrum and this may leak at times. Leg cramps are common at this
point in pregnancy. Your belly button may “pop out” turning from an
“insy” to an “outsy”. Your pelvic ligaments soften to prepare for
birth. You may have swollen hands and feet due to fluid retention.
Once your baby moves down into your pelvis your breathing should become easier again. You’ll need to wee even more than ever. Weeks 37-40
Your
weight gain will slow down now. You may have a show; when the mucus
plug that seals the uterus comes away. Once you reach week 37 your baby
is full term and can be born at anytime. Only a small percentage of
women give birth on their due date, so try not to be disappointed if
you go beyond this. You will be allowed to go up to 2 weeks overdue
before labour is induced. Although you may be allowed to go past 42
weeks if you want to avoid induction, but you will have to be closely
monitored to make sure the placenta is still doing it’s job
effectively. Try to get plenty of rest.
Weight gain during pregnancy
During the third trimester of pregnancy you need to consume an average of 200 extra calories per day.
But before you reach for the biscuit tin, these should come from the following sources: Protein – lean meat, fish, dairy produce, eggs, beans and pulses. Carbohydrates – wholemeal bread, rice, pasta, cereals and potatoes. Fruit and vegetables. Healthy fats such as olive oil, nuts and nut oils, sunflower oil, oily fish and dairy foods.
A healthy weight gain is seen as being between 22 – 35lbs for a single pregnancy.
The breakdown of weight gain is as follows: An average newborn baby weighs in at around 7lb 71/2oz. Placenta 1lb 6oz. Amniotic Fluid 1lb 3oz. Extra Blood 2lb 12oz. Increased Body Fluids 2lb 2oz. Increased Breast Tissue 1lb. Womb (Uterus) 2lb. Increased Body Fat Layer 7lb 7oz.
For a twin pregnancy expect to gain somewhere in the region of 35 – 45lbs.
If you are worried by any aspect of your weight gain, seek advice from your midwife or GP.
Your baby’s head engaging
When
your baby’s head moves down into your pelvis this is known as the head
engaging. This can happen anytime from around 34 weeks to during
labour. On average it happens at 37 weeks but some factors can affect
when this happens. They are: A large baby may not move down to the pelvis until contractions start. If the baby is in a posterior position; when her back is against your back, she may not engage as early. If you have strong stomach muscles, baby may engage later in pregnancy. If you have a narrow pelvis it can take your baby longer to engage. In first pregnancies the head may engage earlier, as subsequent babies tend to drop down near to labour.
Your
midwife will measure how far your baby’s head is in the pelvis by
dividing the head into fifths. Five-fifths into the pelvis means all
the head has descended, where as three-fifths engaged would mean that
three-fifths of the head is in the pelvis. The drawback with this
method is that some midwives measure in reverse, for example;
three-fifths engaged means that three-fifths of the head is still not
in the pelvis. Confused? That makes two of us! Ask your midwife which
method she uses.
On your notes ENG stands for engaged whereas
N/ENG is not engaged. Once your baby has engaged you should feel a
relief from the discomfort you have been feeling such as heartburn and
breathlessness, as it is not as squashed up there anymore.. hurray!
Massaging your perineum
Everyone
wants to avoid tearing or having an episiotomy during birth. By
massaging natural moisturising oils into your perineum (the area
between your vagina and your anus), you can improve the elasticity of
the skin so that it stretches more effectively during birth.
Oils that can be used include: Almond Wheat germ Olive Pure Vegetable Oil Vitamin E
It
would be advisable to start massaging your perineum around the 33rd
week of pregnancy, for a couple of minutes a day. An effective way to
do this is to insert your thumb into your vagina to massage from the
inside, whilst massaging with your fingers on the outside.
Braxton Hicks contractions
Braxton
Hicks contractions; otherwise known as practise contractions were named
after the doctor who first referred to them in 1872. They are caused by
the uterine muscles contracting. You have these contractions throughout
most of your pregnancy, but will only become aware of them towards the
end of the second trimester or during the third trimester. They will
become more apparent the further through pregnancy you get.
Unlike
contractions that you have during labour, Braxton Hicks contractions
are not close together and do not happen regularly. Although they can
become uncomfortable they should not be painful or intense. They will
not become stronger or more frequent, unlike proper contractions.
To ease any discomfort: Have a relaxing bath. Rest in a comfortable position. Try walking around. Drink plenty of fluids.
If the contractions become painful, intense or regular (more than 4 per hour) then consult your midwife or GP.
Pelvic floor exercises
The
pelvic floor muscles stretch along the base of your pelvis. They keep
the bladder closed to prevent incontinence. They enable us to control
when we pass a stool and when we break wind. The pelvic floor muscles
also support the organs in the pelvis. They can enhance your sexual
pleasure and that of your partner when well toned.
One of the
best pieces of advice that you can follow during pregnancy, is to do
your pelvic floor exercises. It is not stressed enough how important it
is too look after them. You should start exercising them from the third
trimester of pregnancy and continue after birth. These exercises should
be done every day.
The best way to find how to tighten your
pelvic floor muscles, is to have a wee and then try to stop midflow,
these are the muscles you need to use. Don’t do this frequently when
weeing, as it can stop you from emptying your bladder properly. Now
tighten these muscles and hold for the count of 10, repeat 10 times.
Then squeeze these muscles and release quickly, do these 10 times. Do
each set of exercises 5 times each per day, fitting them into your
daily routine.
A show – mucus plug
Towards the final
stages of pregnancy, around week 37, you may have a show. This means
that the mucus plug that has sealed the cervix during pregnancy comes
away. It can be lost up to a few weeks before birth. This jelly like
plug is yellowish and can be streaked with blood. You may not even be
aware when this plug has come away. There is no need to contact the
midwife when you have a show, as it does not necessarily mean labour is
about to start.
Waters Breaking
When the membranes of the
amniotic sac rupture, this is known as your waters breaking. Your baby
is protected in this sac surrounded by amniotic fluid, so when this bag
breaks the amniotic fluid is released. Some women experience a gush of
fluid when this happens, whereas others find they leak a small flow of
fluid over a longer period of time.
When your waters break this
usually signifies the onset of labour and the majority of women go into
labour within 48 hours. If your labour has not begun after 48 hours,
the medical team will want to induce labour as there is a significant
risk of infection. Once your waters have broken you should refrain from
bathing and intercourse. The fluid released should be clear, not brown
or green, which would indicate the presence of meconium (baby’s first
bowel movement). Meconium in the waters can show that the baby is in
distress, so you would need to go to the hospital straightaway.
Some
women find that their waters break during established labour. Others
will have their membranes ruptured by the midwife to speed up labour.
In rare cases babies have been born with the sac of fluid still intact,
which is then opened by the midwife.
Birth partner
The
role of a birthing partner is to support you during labour and birth.
They should offer you both emotional support and encouragement. They
also need to be familiar with your birth plan so that they can
communicate your wishes to the midwife. It would be beneficial for your
birth partner to attend some antenatal classes with you, so that they
can remind you on issues such as breathing properly (you will probably
respond to any advise with a variety of obscenities, but this is a good
emotional release for you!).
Hospital policy usually allows one
or two birth partners during a vaginal birth. If you have a caesarean
it will probably be one, check with your hospital to find out their
rules relating to this. In some cases your partner may not be able to
accompany you during an emergency caesarean; this would depend on the
circumstances. During a home birth you could have more people present
(leave room for the midwife though).
Most women choose one or two of the following as birthing partners: Partner. Friend / mum / sister. Doula
– this is a professional birth companion, with knowledge and experience
of birth. She can offer support and advice during labour and birth. She
will meet with you during pregnancy so that she is clear of your wishes
and aims for labour. She can discuss the best way to meet these goals.
She may also be trained in complimentary therapies such as reflexology,
massage and visualisation techniques. A doula can also instil
confidence in a nervous birth partner. The UK Doula Association will be
able to provide you with more information and a list of doulas in your
area. |
