Hamilton is probably not GTA. But it's in the Golden Horseshoe which often symbolizes the Toronto area. Oshawa I am divided on. Could be GTA... or not.
Doctors often order these tests to confirm pregnancy as early as 10 days after a missed period. However, some of these tests can detect hCG much earlier. A quantitative hCG test (beta hCG) measures the exact amount of hCG in your blood. It can find even very low levels of hCG.
Approximately four days after fertilization, the egg will start to produce a pregnancy hormone called human chorionic gonadotropin (hGC). 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.
