What to Expect During the First Trimester

  • For the fetus to develop normally, the first trimester must be healthy. All of the major body organs and systems of the fetus are forming on the inside, even if you may not be showing much on the outside.

  • Several changes occur as the embryo implants itself into the uterine wall, including the production of the.


  • Sac Amniotic: 

During pregnancy, the fetus is surrounded by an amniotic sac, which is filled with amniotic fluid. The fluid that covers the fetal side of the placenta and is produced by the fetus and amnion serves as the fetus's barrier against harm. It also helps regulate the body temperature of the fetus.

Uterus:

The placenta is an organ that grows exclusively during pregnancy and has the shape of a flat cake. It uses microscopic protuberances known as villi to adhere to the uterine wall. These villi house fetal blood arteries, which develop from the umbilical cord and exchange waste materials and nutrients with your blood. A thin membrane divides your blood supply from the fetal blood arteries.

Chord of Umbilia:

The placenta and fetus are joined by a rope-like structure called the umbilical cord. Two arteries and a vein in the umbilical cord transport nutrients and oxygen to the developing foetus and waste products out of it.

The fetus is particularly vulnerable to harm during this first trimester from drugs, alcohol, and some medications, as well as diseases like rubella (German measles).

Both your body and the body of your unborn child are rapidly changing during the first trimester.
