Any ultrasound techs or knowledgable in the area?

Quick question.. I went for a 3d/4d ultrasound at almost 30 weeks . After looking at the video.. I noticed it almost looked like my baby girl had 6 fingers ..although the not very clear. Then I only seen 5 for the rest of the session but I'm wondering how possible is it that maybe she has 6? Her fingers were by her face and I'm not sure if her other hand was there as well at that point . This wasn't at the doctors it was at an elective place .
