Week By Week Pregnancy

1st to 12th week

The first trimester (1st week to 12th week) is the most important part of the week by week pregnancy chart. It starts by the egg getting fertilized by the sperm and then it travels through the fallopian tube. During these weeks the body of the mother undergoes many hormonal changes. These changes can trigger symptoms such as tiredness, nausea and vomiting. Since each woman is different she experiences different symptoms.
