I was put on metformin in Feb 2014 to lose some weight and was not TTC at the time. I never even thought I wanted children until March 26 2014 when I tested because I was switching birth control and that second line popped up. That was one of the happiest days of my life, and then my numbers leveled out, then they dropped, and then I started bleeding. I've never felt that much hurt before. We have been actively TTC since then and every time I POAS is just another sad lonely white line. It's just getting so disheartening, and I just needed to vent my feelings.
