Cord in the middle?

Hey!  Just had our 7w5d u/s and the kidlet is measuring right on track (with hb of 150).  So far, so good.  Though some of the pics showed the embryo's little limb buds better, this one shows the umbilical cord the best (baby is floating upside down).  My ?...is there any guidance on a gender guesstimate when the cord seems to be literally in the middle lol?
