(1) CESSATION OF THE MENSES, OR MENSTRUATION. While it is true that a non-pregnant woman may occasionally pass over a menstrual period, yet as a general rule the complete cessation of a period by a married woman, particularly when the woman has previously been regular in this respect, may be considered a probable indication of pregnancy; and when the second period has been passed the probability merges almost into a certainty. An examination by a competent physician will set all doubts at rest. (2) ENLARGEMENT OF THE BREASTS. This indication usually manifests itself in about six or eight weeks after conception. This enlargement is usually preceded by a sensation of tingling and throbbing. The enlargement is manifested in the form of a rather hard and knotty increase, differing from the ordinary fatty increase; the lobules, arranged regularly around the nipple, are plainly distinguishable beneath the skin by means of the touch of the fingers. (3) DARKENING OF THE AREOLAR TISSUE SURROUNDING THE NIPPLE. In the unimpregnated condition this tissue is of a pinkish shade; but after impregnation the shade grows darker and the circle increases in size. However, when the woman bears several children in somewhat rapid succession, this dark color may become permanent and accordingly ceases to be an indication. (4) ENLARGEMENT OF THE ABDOMEN. This indication manifests itself about the second month, at which time the Uterus begins to elevate the intestines by rising up from the pelvis. In the fourth month the Uterus has risen so far out of the pelvis that it assumes the form and appearance of a hard round tumor. The entire abdomen then begins to enlarge. The Uterus causes an enlargement in the region of the navel at the sixth month, and the region of the diaphragm at the ninth month. (5) QUICKENING, OR "SIGNS OF LIFE." This indication manifests first from the fourth month to the fifth--at about the exact half of the entire period of gestation. At this time, and afterward, the movements of the embryo are plainly discernable to the mother.
