Your Baby
For the first 8 weeks, your developing baby is called an "embryo".  Tiny limb buds, which will grow into arms and legs, appear.  The embryo looks like a tadpole.  The heart and lungs are beginning to form.  By the 25th day, the heart starts to beat.  The neural tube, which becomes the brain and spinal cord, begins to form.  At the end of the first month, the embryo is about 1/2 an inch long and weighs less than 1 ounce.

Your Body
You become pregnant and miss your period.  Your body is making hormones needed to "grow" a baby.  Your breasts are slightly bigger and sore.  If you have morning sickness, try eating crackers.  You may have cravings or hate foods you usually like.  You will urinate more often because your growing uterus is pressing on your bladder.

Prenatal Care Guide
Before you get pregnant, supplement your diet with vitamin B folic acid (found in most multivitamins) to reduce the risk of birth defects of the brain and spine.  Visit the gynaecologist for your first prenatal care check-up as soon as you think you are pregnant.  During the first 8 weeks of pregnancy, all your baby's organs are forming and can be damaged if you smoke, drink alcohol or take drugs.  Ask your health care provider before taking any prescription drugs or over-the-counter products.  Stop smoking and drinking alcohol.  Stop doing street drugs.
