Bride-Liar's Flush

A strange magical disease that at first simply feels like cramp: Pain and the stomach and torso which might be from a bad meal. After a day, the pain subsists. Within nine days the bulge in the stomach can no longer be ignored. Within a month, the afflicted appears undeniably pregnant—regardless of gender.
  They now have the ‘Diseased: Bride-Liar's Flush’ trait, though the condition is not contagious—they will lose 1 Health every time they fail a Health test, and die if they hit zero Health. As their health declines, the disease takes root in their vital organs, congealing and twisting them together. Their tumour-child grows.
  Towards the end, the pain grows again as the target shows signs of organ failure and their pregnancy develops to maturity. When they die, their soul will be immediately reincarnated into the child inside of themselves: their clone then gains awareness and sapience in that moment and must claw their way out of their own corpse before they suffocate to death.
  Once out, the character will appear as they once did when they were about one lifepath old. They keep all of their memeories, but all of their stats reset appropriately, and only about half of their skills and traits are retained (roll a DoF for each).
  Like all diseases, a character can only get this once.
