Now that you know you're pregnant, congratulations! You are now part of the ultimate miracle of life. Although pregnancy is primarily what sustains the human race, not everyone can take part in this magical phenomenon. So consider yourself truly lucky and blessed once you find out that you are expecting.

Pregnancy Basics

Pregnancy starts when sperm fertilizes the ovum or the egg. The fertilized egg is then implanted in the lining of the uterus. This occurrence poses a lot of changes in the woman's body, most notably in her normal hormonal patterns. One of the first signs of pregnancy is a missed menstrual period, which is also the basis used in dating pregnancy. The expected date of delivery would be 40 weeks after the last menstruation. The dating system actually benefits those who have regular menstruation and those who religiously take note when their menstruation starts and ends.

The entire duration of pregnancy is subdivided into three terms. Each term is referred to as a "trimester," where the development of the unborn child follows a particular pattern during the entire 40 weeks of pregnancy. The first few months of pregnancy or the first trimester is the most critical for the developing infant since tremendous development in his/her brain, limbs and internal organs take place during these times. It is extremely important during the first few months of pregnancy to avoid all types of medication unless otherwise specified by certified healthcare professionals. Also, smoking and drinking must be avoided altogether, and even x-ray procedures should be avoided during pregnancy. The following trimesters, although still important, are basically a continuation of what was started during the first trimester. It is safe to say that the first three months of pregnancy act as the foundation of a healthy pregnancy and would in many ways determine the course of pregnancy.

Soon-to-be-moms must also be aware of the different complications of pregnancy and how to avoid them. Also, it is important to get sufficient exercise suited to the stage of pregnancy to ensure an optimum state of health.

Expectant mothers are encouraged to get to know as much as they can about their bodies during pregnancy. Knowing how your body functions while pregnant always empowers a mother-to-be.
