Thanks, Kelly. I had tried probing earlier today and was suspecting it was indeed a female, as I it seemed to stop after 2-3 subcaudals. Tried again when I got home from work and after gently moving the probe around it suddenly hit "the pocket" and slid in with ease about and inch and a half. Definitely different and a bit more difficult than probing other snakes I've dealt with! Thanks again.
