From the moment of conception, a mother's body begins to undergo a dramatic transformation. In order to insure the ability of that transformation to carry through to its completion, certain changes must take place during every stage of each pregnancy. In the earliest stages, some of the almost imperceptible changes go unnoticed by the mother. However, if she observes carefully, she can recognize two very early signs of pregnancy.
There are two tell tale signs that can let a woman know that she could very well be pregnant. One of those signs is actually a group of indicators. Those indicators concern alterations to the physical appearance of the mother's breasts.
As soon as a sperm cell enters an egg cell, then a woman's body begins to make the hormones estrogen and progesterone. That combination of hormones can prepare the cervix for implantation of the fertilized zygote. Once that zygote settles into the lining that makes up part of the cervical tissue, then it becomes an embryo.
Now while the progesterone and estrogen do act on the lining of the cervix, they also affect the breast tissue. They cause the development of milk ducts and the swelling of tissue in the region of those ducts. At the same time, they cause the nipples to darken, along with the area around the nipples.
After the embryo settles into the lining of the cervix, then that embryo begins to grow, and the uterus starts to expand. That expanding uterus produces another significant change. It presses on the bladder, and it makes a young mother feel as though she always wants to relieve herself. That almost constant urge serves as yet another signal that a woman is likely to be pregnant.
Now once a woman realizes that her body is undergoing those two specific changes, then she ought to plan on speaking with her physician. She should also examine her lifestyle, to see if she might be doing something that could harm her developing child.
A woman who is a diabetic, or a female who has another chronic medical condition needs to understand that she will experience a "high risk pregnancy." She needs to see a physician as soon as possible.
