Quoting Squeaky McGee:" Are the doctors sure you're miscarrying? Was it the same brand of test? Same time of day? A lot of factors can effect how dark the line is. I'm sorry you're going through this."
Quoting Becky☮Will:" How much did you bleed? I'd say either your pee was just more concentrated this time, or maybe you didn't actually miscarry."
Quoting luvmy2grlz!:" Are you still having bleeding? Are you having any cramping? Is it possible your placenta is covering your cervix right now? Oh I hope you get good news tomorrow."
