How soon can I know if I am pregnant?
The first sign of pregnancy might be your missed period. If you are pregnant, most pregnancy tests will show a positive result by the time you have a missed period. Some pregnancy tests even work a few days beforehand. Read the label on the pregnancy test box to see when the test may become effective.
Other early signs of pregnancy include fatigue, feeling bloated, frequent urination, mood swings, nausea, and tender or swollen breasts. Not all people have all of these symptoms, but it’s common to have at least one of them.
Most women wonder if they’re pregnant many times in their lives. Our Am I Pregnant tool will help you find out if it’s time for a pregnancy test. Or learn more about pregnancy on our website.
