At eight weeks, the embryo is called a fetus. The placenta, which is what keeps the baby alive, is being formed.
The mother experiences many of the same symptoms as the first month, along with increased vaginal discharge. Another symptom she may suffer is a bad complexion. This acne is caused by the hormonal changes the mother's body is undergoing. The mother will also experience an increased metabolism. .
During the third month of pregnancy, the uterus is a little bigger than a grapefruit and can be felt just above the pelvic bone. Measuring 2.5 to three inches long and weighing 1.5 ounces, the fetus is about the "size of an apple" (Murkoff 155). The baby's head, which makes up half of his length, now sits on a neck. The baby's eyes get closer, and his ears move to the sides of his head. The baby's reproductive organs will be undergoing development. Twenty teeth are forming under his little gums as he starts to suck. At this point, the fetus produces urine, which he releases into the amniotic fluid. The baby's heartbeat can be heard with a Doppler during the third month.
The mother may develop some new symptoms this month. She may suffer from constipation and flatulence. Bloating is another common symptom among mothers during their third month. Other common problems she may go through include heartburn and indigestion. These are often caused by the fetus" position against the mother's stomach.
During the fourth month, both mother and child go through many changes. Having grown to the "size of a small melon," the uterus can be felt about 1.5 inches below the mother's belly button (Murkoff 173). The fetus is about five inches long and weighs five ounces. The baby grows more this month than any other month. His body has grown to be more proportional to his large head. The baby's fingerprints and toe prints can now be detected when baby isn't sucking his fingers, which he now does. The fetus can also swallow and breathe the amniotic fluid.
