Case Study #1
The zygote is the size of a pin head. The egg is attached to the lining of the uterus. The zygote is
attached to the lining of the uterus and becomes an embryo. The mother has missed her menstrual cycle,
her breasts have enlarged, and she has to urinate frequently. What month is this?
Case Study #2
The fetus is 17-18 inches long and weighs 5-6 pounds. The fetus continues gaining weight until the week
before birth. The skin becomes smooth as fat deposits continue to develop. Movement decreases as the
fetus has less room to move around. The fetus acquires antibodies to fight disease from the mother’s
blood and moves into the pelvis, ready for birth. The mother feels lightening as the fetus drops into the
pelvis; breathing becomes easier. Other discomforts continue, and a total weight gain of 25-35 pounds is
typical. False labor pains called Braxton Hicks contractions may be experienced. What month is this?
Case Study #3
The embryo is ¼ inch long and has developed face, eyes, ears, and limbs. The bones have begun to form.
The embryo changes to a fetus and remains a fetus until birth. The mother has swelling of breasts and
increased urination due to pressure on the bladder. She is not having nausea or morning sickness. What
month is this?
Case Study #4
The fetus is 3 inches long and weighs one ounce. The fetus can suck its thumb, swallow, hiccup, and
move around. The facial features become clearer. The mother’s abdomen continues to grow slowly.
Most discomforts of early pregnancy, such as morning sickness, usually are gone. Appetite increases.
What month is it?
Case Study #5
The fetus is about 8-10 inches long and weighs about 8-12 ounces. The mother senses fetal movement as
strong kicks, thumps, and bumps---some may be visible. The mother gains as much as 10-12 pounds
during this month. What month is it?
