They are called tarsal spurs. What I am referring to is the movie. It under care sheets. Look under Veils. It is a liitle hook on their heel. From the size of your veil, and the pattern, it is an easy guess to to the sex. But you didn't ask the question, so I didn't answer. I treat it like the pregnant lady who gets an ultrasound. Just because you can know the sex, doesn't mean you always want to right away. Some want to wait and see. Otherwise, there is a section for asking that question. If she wanted to know, I think she would have flat out right asked.
