The Convenient Online Pregnancy Test
If you think you might be pregnant, but aren't sure if you need to go out and spend the money on a home pregnancy test, you can visit any one of a number of Web sites that offer an online pregnancy test. Unlike a home urine test, an online pregnancy test can't give you a definite yes or no answer. It can tell you if there's a chance you're pregnant, basing the answer on your replies to questions in the test.
Your answer will be expressed as a percent – for example, "Based on one occurrence of unprotected sex on the day you entered, there is a 15% chance of pregnancy." The online pregnancy test will never give you a higher chance than the statistical probability – that is, it will never say there is a 90 percent or 100 percent chance of pregnancy. The statistical chance of becoming pregnant in any one month, even with unprotected sex at the most fertile time, is only about 25 percent, so you will never receive an answer much higher than that figure.
An online pregnancy test is easy and takes only a few minutes to complete. You will be asked to supply facts such as your age, the average time between your periods, and the first day of your last normal period. (Some test sites supply calendars to help you pinpoint precise dates.) You will also be asked what date you think you got pregnant, and whether or not you had intercourse on other days around that time.
Some tests will then go on to ask you about symptoms you might be experiencing, such as fatigue, nausea or vomiting, and swollen, tender breasts. You might also be asked what kind of birth control you were using at the time. Once you've filled in all the dates, simply press the button and wait for the results of your online pregnancy test.
Most sites point out that an online pregnancy test is not a diagnosis and should not be considered medical advice. No matter what the statistical probability that you are pregnant, most sites will tell you that if you suspect pregnancy, you should call your doctor and have a blood or urine test done.
