Early Ultrasound

Ashley • Will be meeting our first in August 2015!!!
Did anyone see only one little bean in their early ultrasound and then later find out there's two? Measuring 5w6d today for my very first scan but my grandma has 3 sets consecutively so I'm imagining it will pass to me eventually. Just curious if the one we saw today could soon show as two or if this one little dot is good to go for the next 8 months.
