Amantila, i did the same research and it can be sign but, not definite sign. I just tested at 10dpo because, I was back home early then expected so saiwhyd not. But, ofcourse with 2coffees, water and apple juice before test won't give me anything for sure this early. Although, I doubt ita am pregnant.
i will test with fmu tomorrow and update.
fx that thia is sign for us.
