You can also look back at cape fear constrictor post about follicular development. Some snakes will ovulate sooner than expected depending on how big the follicles are from the start of the pairing. Some will take months to develop. He had some graphs that showed several females growing their follicles. I know a breeder that ultrasounded one female and she already had 20mm follicles without even introducing the male. But like Deborah said it is way too soon to even talk about ovulation. I have a snake that has been paired since September and she was cooling a bit and still eating but now she's off food for the last two weeks and I'm only thinking she is starting to get gravid. You will know when she is with eggs when you see that huge bulge down near the end of the body and she has not eaten for a while.
