During human gestation, rudiments of all organs develop in the first trimester.
<h3>What is the first trimester?</h3>
- Most people (including your doctors and midwives) divide a full-term pregnancy, which lasts about 9 months, into three 'trimesters'.
- The first trimester of pregnancy is measured from the first day of your last period to week 12, even though you are pregnant from the moment of conception, when a male sperm fertilizes your ovum (egg), when you become pregnant.
- This is so that the majority of women who conceive naturally won't be aware of the conception date.
- Because the changes that occur to you and your unborn child fall into the three general categories of early, middle, and late pregnancy first, second, and third trimesters are a useful way to think about pregnancy.
