=Salivation.=—The excessive secretion of saliva often accompanies the morning sickness. The secretion is tenacious and difficult of expectoration. Heartburn, abnormal appetite, longing or loathing for particular articles of food, toothache and the like may be present. =Quickening.=—The first feeling of fetal life felt by the mother is usually between the fourth and fifth months, but may be experienced occasionally as early as the third month, or be deferred until the sixth. Quickening occurs as soon as the uterus comes in contact with the abdominal wall. Improper elimination of the bowels, causing gastro-intestinal trouble, may produce movements not unlike this indication; therefore, this symptom is not reliable. =Enlargement of the Breasts.=—The breasts grow larger toward the end of the second month. In some cases the enlargement is very marked, but in others there is scarcely any increase in size during the whole term of pregnancy. =Pigmentation.=—Coloring of the skin takes place in different parts of the body. The face may show brownish spots. The skin darkens in the axilla and in the areola of the breasts. A dark line presents itself down the middle of the abdomen. The vagina takes on a violet tint, the cervix becomes purple, the various colors becoming more marked with the progress of pregnancy. =Changes in the Abdomen.=—The abdomen grows larger gradually, and with it the gait and carriage of the woman change, to counterbalance the weight of the abdomen. It enlarges symmetrically unless the uterus is displaced by adhesions, or by a tumor in the uterus or external to it. The tearing of the under layer of the skin of the abdomen while distended produces streaks (stria), first pink and then white, which remain after the form resumes its natural shape; any other enlargement of the abdomen, especially when caused by a tumor, may produce the same result. The various conditions mistaken for pregnancy, due to changes in the abdomen, are fibroid in uterus; metritis; swelling of the tubes and ovaries, distended bladder, a pendulous belly; excessive fat; extra-uterine pregnancy; and inflammatory conditions, such as peritonitis. Pregnancy and any of the conditions named may coexist, and the former may be overlooked, while the latter is recognized. =Fetal Heartbeat.=—The heart sounds are generally audible between the fourth and fifth months. The rate is from 120-140 a minute, being double that of the mother’s pulse. About midterm is heard the uterine souffle, a blowing sound, quite unlike the fetal heart, and its origin is the rushing of the blood through the enlarged and twisted arteries. =Ballottement.=—In normal cases there is no pain on palpation. The uterine wall varies in consistence, being alternately soft and firm. The fetal parts may be felt through the abdominal wall in the late months.
