It is recommended to test with first morning urine which has the highest concentration of hormones.

Home pregnancy tests performed correctly 99 percent reliability, which means that there is one per cent of the exceptional cases that can go wrong.

How do home pregnancy tests

home pregnancy tests have a device that contains antibodies, associated with HCG to get the color, which will show signs of the results.

If negative: 
 you do the test three days later to rule out the possibility that your HCG level is low and not detected. If you get a pregnancy test prior to the date, or before a minimum delay of a day, is likely to give false negative results, and you might be pregnant. If still negative and your period comes, you must go to the doctor to discuss the delayed menstruation or exclude each other complications, such as ectopic pregnancy (when the embryo implants in the fallopian tubes).

If positive: there is no change even leave the device in contact with the urine of more than five minutes and you should consult your doctor about your pregnancy, although they do not feel symptoms of pregnancy. False positive occurs if you have a pregnancy Anembryonic (without an embryo or an empty bag), but the results will be positive because the embryos implanted in the uterus will begin producing the hormone HCG, but the pregnancy will not develop.
