I'm so mad at this company, because I can't just embrace that it is really a girl. Even though the tech was 100% sure and you can clearly see three white lines. What if the big ultrasound was done to early (I was almost 18 1/2wks) or what if my baby has something wrong with his penis. I just can't get these thoughts out of my head.. I just hate hate hate TMPOB!!!!!!!!!!!!!!!!!!!!!!!!!!!
