Knocked up, eggs in all holes (queen of the deep). Encounter Bothrioc Quadomme. It defeats me in combat, finds out I'm knocked up and punishes me. The final text in the description says "You defeated the bothrioc dominatrix! 173,339 XP gained. I did this twice just to be sure and I got XP both times (although the amount varied modestly). Before the third attempt, I checked my XP in my codex, found another encounter, checked my XP and it had indeed increased.
