The first trimester is a time of excitement for the parents to be and it is a busy time for the fetus that is busy growing body systems and organs. Once the embryo has implanted in the uterine wall the amniotic sac begins to develop and fill with amniotic fluid. This fluid will protect the baby throughout the pregnancy and help in maintaining temperature. The placenta and umbilical cord also develop during this stage of pregnancy.

During the first trimester the fetus is sensitive to drugs, alcohol, medications, and some diseases. The mother’s body and fetus’ body will undergo significant changes during the first trimester.

The embryo will grow to three to four inches long and weigh ½ to 1 ounce during the first trimester. This seems really small, and it is, but rapid changes are taking place. Each fetus develops at his/her own rate and doctors will monitor the growth at each appointment. The first appointment your doctor will likely conduct an ultrasound to see the baby and its heartbeat. That is an experience that is worth all the pain and discomfort that comes from pregnancy because you can see your baby’s tiny heart pounding away.

During the first trimester women are usually exhausted and suffer from morning sickness. Some women have extremely sore breasts while others notice their sense of smell is stronger than ever. What’s important during the first trimester is to get as much rest as possible, take prenatal vitamins, and relax. The pregnancy should be an enjoyable time and memorable. The best way to do this is let others help you and realize all the changes your baby is going through in such a short period of time.
