Your fetus is now about one inch long. The head has straightened out and is more fully developed, the ears are much more prominent and some new organs (the liver, spleen and gallbladder) are forming. Your fetus is also making spontaneous movements of his or her arms and legs now that minuscule muscles are beginning to develop
Diet and exercise go hand in hand so keep in mind not to even miss one day of some sort of exercise in order for your pregnancy to be fruitful.
