2. Changes in the breast.
3. Morning sickness.
4. Disturbances in urination.

Menstruation may be interrupted by other causes than pregnancy, but
the missing of the second or third periods usually indicates
pregnancy. Accompanying the cessation of menstruation, changes in the
breast occur. Sensation in the breasts akin to those which usually
accompany menstruation are manifested at this time in connection with
the unusual sensations of stinging, prickling, etc. Fully one-half of
our patients do not suffer with "morning sickness;" however, it is the
general consensus of opinion that "morning sickness" is one of the
early signs of pregnancy, and these attacks consist of all
gradations--from slight dizziness to the most severe vomiting. It is
an unpleasant experience, but in passing through it we may be glad in
the thought that "it too, will pass."

Because of the pressure exerted by the growing uterus upon the
bladder, disturbances in urination often appear, but as the uterus
continues to grow and lifts itself up and away from the bladder these
symptoms disappear.

Chief of the later signs of pregnancy are "quickening" or fetal
movements. The movements are very much like the "fluttering of a young
birdling." They usually are felt by the expectant mother between the
seventeenth and eighteenth weeks. This sign, together with the noting
of the fetal heartbeat at the seventh month, constitute the positive
signs of pregnancy.

PROBABLE DATE OF DELIVERY

And now our expectant mother desires to know when to expect the little
stranger. From countless observations of childbirth under all
conditions and in many countries, the pregnant period is found to
cover about thirty-nine weeks, or two hundred and seventy-three days.
There are a number of ways or methods of computing this time. Many
physicians count back three months and add seven days to the first day
of the last menstruation. For instance, if the last menstruation were
December 2 to 6, then, to find the probable day of delivery, we count
back three months to September 2, and then add seven days. This gives
us September 9, as the probable date of delivery. The real date of
delivery may come any time within the week of which this calculated
date is the center.

As a rule, ten days to two weeks preceding the day of delivery, the
uterus "settles" down into the pelvis, the waist line becomes more
comfortable, and the breathing is much easier.
