There are three stages of pregnancy. These are the first, second and third trimesters. The first trimester runs from week one to week fourteen, the second covers weeks 15 - 26, then the third is weeks 27 - 40.

Week 1+2: This is actually before you get pregnant. It's the stage where your body prepares itself by ovulating. And it's in these 14 days that the egg is fertilized by the sperm

Week 3: The fertilized egg now moves down the fallopian tubes, fluid passes into the ball of cells, dividing them into two. The inner cells will form your baby and the outer cells will form the placenta. Your body, at this stage, is still unaware that it is pregnant. The implantation begins as the cell ball reaches the wall of the uterus. In this process the cells actually bury into the uterus wall, which can sometimes lead to you having spotting. The implanted cell ball now becomes an embryo.

 

Week 4: This is a week of rapid development, and your body now realises it is pregnant. The amniotic sac and cavity begin to develop and also the Yoke sac appears (this will later form the baby's digestive system). The placenta now starts to form where implantation took place and blood from you will now go into the placenta. It is usually about day 27 that we start to feel the morning sickness.
