Pregnancy Symptoms (cont.)

Missed Period

Perhaps the best known sign of pregnancy, a missed period is generally the hallmark symptom of early pregnancy. However, women who do not have regular menstrual cycles may not detect this important sign. Furthermore, some women experience a small amount of vaginal bleeding or spotting about 6 to 12 days after conception, around the time of their expected menstrual period. This is known as "implantation bleeding" and is generally not as heavy as a typical menstrual period.

It is important to note that a missed period does not establish the diagnosis of pregnancy, even if other symptoms of early pregnancy are present. A number of both physical and emotional factors can be responsible for missed or skipped periods even in women who have regular menstrual cycles.
