Dots or lines can show up on either sex. It just depends on the angle. That's a very nice pic of early girl parts, dots and all.
Would it help you to post your 15-week video and let us look at it? I'm 100000000% sure that every shot you've posted is a girl shot, but maybe it would reassure you for people to verify that no boy parts show up anywhere in your scan.
Edit: nm, I just realized that this was your 13-week video. I remember seeing this shot now. I thought and still think it's a very very girly shot. Combined with the nub shots, I just don't see any way this baby will come out a boy.
