Thanks for your thoughts, guys. She's been eating like clockwork. Last time she ate was a medium on Wednesday of last week (10/1). There's no way this bulge was from that.

Also, I checked in on her this morning, and she seemed to be back down to normal size. I came into this whole thing fully expecting to be pairing them for months before getting any eggs. For my own sanity, I'm going to act like this wasn't ovulation---but if it wasn't it, I'm excited to see what is. Her bottom third looked HUGE compared to normal when I opened her tub. My first thought was "this is the real deal." Time will tell, I guess. We can all look back and laugh when she lays her eggs in March.

I'm definitely going to keep introducing the male for as long as it takes.
