Anna M. Galbraith, The Four Epochs of Woman's Life…
“ The danger of miscarriage is greatest during the first three months of pregnancy. Miscarriage is a fruitful source of disease and often of danger to wives; it is said that thirty-seven out of every hundred pregnant women miscarry. Miscarriage is most apt to occur during the first pregnancy; and great care should be taken to prevent this, as the habit is easily established, and after one miscarriage has occurred, another is likely to follow, so that it is sometimes with the greatest difficulty that the woman can be made to carry the fetus to full term. ”
