HOW THE WOMB IS HELD IN PLACE.--The human uterus, or womb, is held in its proper place in much the same way as a clothes pin sits on a clothes line. The heavier part is the upper part, and that part is held in place partly by resting on the rectum behind, and the bladder in front. When menstruation occurs, the body of the womb becomes much heavier because of the increased amount of blood in its interior. This added weight increases its liability to tip over, and if any extra strain or effort is made at this time it will become tipped, or as the physician calls it, displaced. If a womb becomes displaced, every menstruation afterward will be painful and prolonged,--sometimes excessively so. A displaced womb becomes congested and unhealthy. It causes leucorrhea or a chronic discharge, makes a nervous wreck of the woman, results in sterility and frequently in a dangerous operation. There are, therefore, ample reasons for watchfulness and care on the part of the growing girl. SYMPTOMS OF MENSTRUATION.--After menstruation is established there should be no actual pain at each period. There are, however, certain undefined feelings,--premonitory symptoms,--which may be explained in the following terms:--A day or two before the date on which the menstruation is expected, the girl will appreciate that "her sickness" is coming. She will not, or should not, complain of pain, but will state that she has a bearing down feeling, is a little more nervous than usual, has no desire to go into company, and wants to be more or less her own entertainer. The "sick" period usually lasts four or five days. The second day is the most important. MENSTRUATION SHOULD NOT BE ACCOMPANIED WITH PAIN.--If any actual pain accompanies menstruation, either before or after it is established, the mother should at once take the daughter to the family physician. Menstruation is a natural, physiological act and should not be accompanied with actual distress or pain. It is astonishing how many mothers will allow their daughters to suffer needlessly, for months and years, because of the mistaken idea that "since the pain is there, it must be," or because she--the mother--suffered, so also must the daughter suffer. There is no more unfortunate mistake, and many a girl's health and happiness has been blasted because of this misbelief. The cause of the pain is, in a vast majority of the cases, a very simple one, and can be removed in a very brief time.
