"Well, yesterday was my 'what's it going to be' ultrasound. And after much anxiety and anticipation we are going to wait longer to find out. The baby was in a position where the gentiles were not able to be seen at all..."It's "genitals," ma'am. Genitals. Or genitalia. Your choice.
In any case, mazel tov!
Note: If you Google "gentiles," this picture comes up. We did NOT Google genitals. Not tonight, anyway.
