How can you tell you are pregant?

Pregnancy: The best way to tell is to do a home pregnancy test after a missed period. These are inexpensive, easily available and reliable. The also give an answer long before all the old-fashioned signs of pregnancy that we used to rely on before urine pregnancy tests were available. A little modern miracle of medical science. Use it.

Within 5-7 days: Over-the-counter tests can accurately detect pregnancy within 5-7 days of a missed period. However, if you have irregular periods, or you have been on birth control (but not consistently), then you should see your doctor to get a blood test.
