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.
A pregnancy test will detect this hormone about one week after fertilization. Most women tend to wait to take a pregnancy test until after they have missed one menstrual period. If you take a pregnancy test one week after you were supposed to get your period, the result will be about 95% accurate. If you take it too soon after fertilization, it may show up negative when in fact you really are pregnant. Pregnancy test are meant to be considered screening tests. If your test comes up negative, but you are experiencing symptoms of pregnancy you should call your doctor.
