Sun and Light. Of all of the Gryphon's symbolic traits, this one is the most powerful, long lasting and unyielding of them all. It should be pointed out that the two creatures which comprise the Gryphon, eagle and lion, are both strongly connected to the Sun to begin with.
Most pregnancy tests include instructions that encourage you to wait at least one week between a negative test and taking another pregnancy test. This is to allow time for your body to build up enough hCG (human chorionic gonadotropin) to be detected in your urine.
Since the test will not get a positive result until enough HCG is present in the urine, home pregnancy tests work at varying points from the time of conception. According to the Mayo Clinic, most pregnancy tests will not show a positive result until at least one day after your missed period, or about 12 to 14 days from conception. The one exception to this rule is the First Response Early Pregnancy Test, which has shown the ability to detect pregnancy up to five days before your period.
