I missed my period for the very first time EVER! 18 years of menstruating and I've never ever missed or even been late. So, of course, I tested! It came back negative. I'm 4 days late. The tests say accuracy is high the first day of missed period. Is this false? Does it take longer to show? I didn't even realize anything until I was already 5+ weeks with my last 2 kids so I'm not sure about earlier testing. :-( I'm just feeling confused and discouraged.
