Depending on the date of your menstrual cycle and some simple calculations based on the date you had intercourse, these online pregnancy tests will determine whether you are pregnant or not.
An important point to remember while taking the online pregnancy test or quiz is that it is just a probability that these tests indicate. These tests cannot be relied on, and do not accurately confirm a pregnancy. They just give a possible or probable result. These tests cannot replace actual blood or urine tests that detect the human chorionic gonadotropin, or HCG hormone produced by a woman’s body during pregnancy.
If these tests give a positive result, then you may use a home pregnancy test kit (HPT). These kits claim that they can accurately detect a pregnancy before the following menstrual period. However, if the tests come out negative, you may wait for a week or so after your menstrual date and then repeat the test. For confirmation of a pregnancy, you need to visit a doctor who will conduct urine and blood tests for the same.
