The eighth week of pregnancy is an exciting time for expectant parents because the embryo is now officially called a fetus. At this stage, the fetus is about the size of a kidney bean, measuring about 0.6 to 1.0 inches (1.6 to 2.5 centimeters) from crown to rump and weighing around 0.04 ounces (1 gram).
Here are some developments you can expect during this stage:
Facial features: The fetus’s facial features continue to develop, with the eyes becoming more prominent and moving closer together. The ears and nose also start to take shape.
Limb development: The limbs continue to grow and develop, with the fingers and toes separating further. The hands and feet may also start to move.
Organs: The major organs such as the liver, kidneys, and lungs start to function. The digestive system also starts to develop, with the intestines forming and moving from the umbilical cord into the abdomen.
Genitals: The genitals begin to develop, but it may still be difficult to determine the sex of the fetus through ultrasound.
Heartbeat: By the eighth week, the heartbeat of the fetus is strong and can be detected by ultrasound.
Brain development: The brain continues to develop, with the cerebral hemispheres becoming more distinct. The nervous system also starts to develop, with the fetus being able to make small movements.
Amniotic fluid: The amount of amniotic fluid increases, which helps protect and cushion the fetus.
During this stage, it is important to maintain a healthy lifestyle to support the development of the fetus. This includes eating a balanced diet, staying hydrated, getting enough rest, and avoiding alcohol and tobacco.
It is also a good time to schedule your first prenatal appointment with your healthcare provider to ensure that you and your fetus are both healthy and on track for a successful pregnancy.
