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.
I used the First Response pregnancy tests and it claims that it can give you results up to 6 days before your missed period and that most women get accurate results within 4 days of your missed period. I thought I felt pregnancy symptoms (upset stomach, increase discharge, exhaustion).
