Please dont worry chick. With my daughter i had to go back because they couldnt see her spine, she was in the wrong position, so went back a week later and they got everything they needed. With this one (also a girl) she wasnt moving at all, i was so worried, they sent me back 3 weeks later because as she wasnt moving they couldnt see her lower limbs or her heart or face. Well the second scan was a different story, she wouldnt stop moving!!! Think she was just having a lazy day, and i posted on here because i was worried she didnt move much and lots of people told me that they had the same thing, im sure if the sonographer was worried about something she would have told you. Hope everything goes well anyway, im sure it will! x
