Eggs? Ovulation? Building? Something else entirely?

Yes, and that is why I am also very confused.

I bought her January 30th and she has been in quarantine since. She has not been introduced to any of my other snakes, nor will she be. (I had no plans of breeding BPs within the next few years).

That does not mean she was not bred before you got her or even last year. They can and sometimes do retain sperm. And yes she is gravid and going by the pics looks like 5 eggs.
