The absence of a menstrual period often is one of the first indications you are pregnant. Other early signs may include enlarged and tender breasts, needing to urinate frequently, feeling unusually tired, slight weight gain, and nausea or vomiting.
If you suspect you are pregnant, it’s fine to use a home pregnancy test (which detects a fetal hormone in the urine). These tests are not always reliable, so if the result is negative and you still think you are pregnant, you should see your health care provider, clinic or health-care center for more accurate testing.
One reason to see your health care provider is to make sure you don't have an ectopic pregnancya circumstance in which the pregnancy develops outside the uterus, usually in the fallopian tube. Ectopic pregnancies are often missed by home pregnancy tests because the fetal growth hormone is present in much lower amounts than when the pregnancy is uterine. Though relatively rareectopic pregnancies occur in about 1 in every 100 pregnanciesthe condition can become life-threatening and requires surgery.
