The first trimester begins on the first day of your last period and lasts until the end of week 12. This is the beginning of your pregnancy and is a very important time for its development. Even though it may not seem like much is happening in the early days of pregnancy, the most dramatic changes and development happen during the first trimester as the embryo implants itself into the uterine wall.

A sac filled with amniotic fluid, called the amniotic sac, surrounds the foetus throughout the pregnancy. The amniotic fluid is liquid made by the foetus and protects the foetus. It also helps to regulate the temperature of the foetus.

The placenta is an organ shaped like a flat cake that only grows during pregnancy. It attaches to the uterine wall with tiny projections called villi. Foetal blood vessels grow from the umbilical cord into these villi, exchanging nourishment and waste products with the mother's blood.

The umbilical cord is a rope-like cord connecting the foetus to the placenta. The umbilical cord contains two arteries and a vein, which carry oxygen and nutrients to the foetus and waste products away from the foetus.

During the first 8 weeks, a foetus is called an embryo. The embryo develops rapidly and by the end of the first trimester it becomes a foetus that is fully formed, on average only 3 to 4 inches in length. That is a lot of growing in the first 12 weeks!

Make sure to look after yourself during this time. It’s common to experience morning sickness, cramps, tender breasts, tiredness and fatigue during the first trimester. You may need to rest more or eat smaller meals during this time. Or you might be one of the lucky ones who doesn’t feel any of these symptoms at all.
