Nine Months : Mother and Baby Watch (Trimester 1)

WEEK 1-4

Conception would have taken place around 2 weeks after your last menstrual period (LMP) if ovulation coincided with the release of your partner's sperm into your body.

You And Your Body

You will be unaware of the changes taking place within your body although some women just know' that they have conceived! You may experience very slight bleeding at the time when your next period would have been due. This is probably the first real indication that you may be pregnant.

Your Baby

* Your baby (called the embryo from now till week 6) is really tiny and can't be seen with the naked eye.

* Although still tiny, it has complete information about whether it will develop into a baby girl or baby boy.

* The beginnings of nerves, skin, bones, cartilage, muscles, circulatory system, kidneys, sex organs, respiratory and digestive systems, are laid down in the form of layers.

* It is amazing how your baby started the journey of life with a single cell and is now about 100 cells strong and still growing.

* Your baby has found its home and lodges itself in the womb where it will stay for the next nine months floating in a fluid-filled sac called the amniotic sac. This sac is a very powerful shock absorber and hence, protects your baby.

* Even from this young a stage, your baby has a mechanism in place whereby it can link with your blood supply. This mechanism will develop into the placenta, your baby's life support system.


You And Your Body

This is the week when you will miss your scheduled period and will be able to confirm your pregnancy officially using a test. You will also be able to calculate your due date. Although some women sail through the early days of pregnancy, some may start feeling the pregnancy sensations from the very start. These may include:

* You may start feeling very tired even at this early stage.

* Breasts may be tingling or very tender.

* Nipples may start to appear darker than usual.

* Veins in the breasts may become more prominent.

* Strange metallic taste in the mouth.

* Going off tea and coffee.

* Morning (or anytime) sickness or a general feeling of nausea.

* Increased urge to urinate.

All in all, your body is gearing up for the next nine months ahead!

Your Baby

Your baby is only just visible to the naked eye and measures only about 4mm in length. The spinal cord and brain have started to grow and the beginnings of the heart is laid down in the form of a blood vessel.


You And Your Body

If you are suffering from nausea or morning sickness, you may find that it starts to get worse. This is due to the increased levels of the pregnancy hormone in your body now. You may also start to feel tired and irritable.

Your skin will become either spotty or extremely dry. This is natural. Its just the hormones at work again!

Your Baby

* Your baby is the size of an apple pip now and measures about 6mm in length.
