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.
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.
