There can be no doubt that the often excessive loss of blood leaves the woman in a weak and rundown condition, thereby lessening her powers of resistance to other diseases. The shock to the woman's system is greater than that produced by natural labor, and consequently leaves her in a hysterical and often critically nervous state for some time after. The causes of abortion are many. Among them are overexertion, overexcitement, shock, fright, fall, great anger, dancing, fatigue, lifting heavy weights, purgative medicines and excessive sexual intercourse. The dangers resulting from abortion are blood poison, hemorrhage—even lockjaw has been known to be the result of abortion, also the danger that one miscarriage is likely to follow another, and disables a woman to carry a child to the full term. If there is the same care and treatment given the woman who aborts as the woman in childbirth, she will naturally be less likely to suffer serious results than if no medical attention were given her. One of the most common disturbances of pregnancy is nausea, more commonly called “morning sickness,” because it is felt in the morning when the woman first assumes the erect position. As a rule, this lasts only during the early months. About the latter part of the fourth month, or often not before the fifth month, movements of the foetus are felt. These movements are called “life”, and women are glad of this signal that all is progressing naturally. One writer said a woman had described the first feeling of life as “the trembling movements of a bird within the hand.” There are often many nervous manifestations accompanying the pregnant woman, such as headache, neuralgia, toothache and as a usual thing, constipation is always present, and should receive attention. The teeth also should receive attention at this time for they decay easily on account of the secretions in the mouth which are increased during pregnancy. The breasts enlarge in the early months of pregnancy, and there is a fullness and tingling felt often in the fifth week. The nipples become erect and the skin around the nipple becomes dark brown. These are only a few of the disturbances of pregnancy, but enough to show that other organs beside the uterus are tested in strength and how important it is to have a good healthy body. In fact, every tissue and fiber in the woman's body feels the impetus of pregnancy, and all kinds of physical changes occur. Like in June, “Every clod feels a stir of might, an instinct within it that reaches and towers.”—Howell. One of the common questions asked by young women in early married life is how to tell if they are pregnant.
