Week 1
Right know your baby is just a bundle of tiny cells that are
growing very quickly as they journey along the fallopian tube.
Remember to eat well.
|
Week 2
By now the fertilised egg has arrived in your uterus and has
made itself at home in the lining. The placenta is beginning
to form around it.
|
Week 3
During your third week expect a period of rapid growth with
amniotic activity and yolk sac developing. The placenta also
begins to develop and the chorionic villi, the tissue lining
the placenta begins to form also. Morning sickness could set
in around this time of your pregnancy. It sometimes can be
improved by eating small meals more frequently. Don't worry
it wont last long!
|
Week 4
The next 10 to 30 days are crucial in the development of the
nervous system and heart. So drink plenty of fluids. The forerunner
of your baby's brain and spinal cord are evident at this stage.
The baby's head is now detectable. Three layers of tissue
are forming in week 4 they are: ectoderm, mesoderm and endoderm.
Ectoderm will form skin, hair, lining of ears, nose, mouth,
glands and nervous system. From the mesoderm, your baby will
develop muscles, bones, blood cells, heart, lungs, and excretory
and reproductive systems. From the endoderm, your baby will
develop glands, bladder, tongue and digestive tract.

Week
5
Tiny buds that will form the arms appear. Lower limb buds
appear. Eyes, liver and digestive system begin to form at
this stage. Your baby is still only tiny, the size of an apple
seed, but the spine is already forming. An ultrasound can
now reliably detect the fetal heart. The embryo is now 8 mm
long. Oral and nasal cavities are now forming. Cerebellum
and spleen are also beginning to develop. Baby's upper limbs
bend at elbow and external ear is beginning to form.
|
Week
6
Not only is your baby growing, but you're starting to feel
different too. You may also be experiencing nauseous at this
time. If you have been suffering from heartburn since becoming
pregnant you might want to try eating smaller meals more often.
The tip of your baby's nose is now distinct. Eyelids are beginning
to form.
|
Week
7
Intestines have formed outside the baby on the umbilical cord-
they can't fit inside yet. Your blood pressure is lower than
usual, so you may experience feelings of dizziness or even
fainting.
|
Week
8
Your baby is no longer an embryo, now begins the fetal period.
He or she is free floating in amniotic fluid, but you can't
feel the movements yet. Good nutrition is extremely important,
so make sure you eat lots of whole grains, fruit and vegetables,
which will give you and your baby the vitamins and minerals,
you need to grow.
