Kel knew the ramifications of revealing her pregnancy. She didn't even tell Faleron until a week before she revealed it to her King. The men in her life would just worry.
As it turned out, she did well. She didn't start to show until she was about five months pregnant. She told people at five and a half, and was not allowed to hold a sword from that point onward.
When she was eight months pregnant, it was winter, so she was on house arrest. She finally got cabin fever and snuck out into the snow to draw a long bow. She got twelve or thirteen glorious shots at the target – she hadn't lost her touch, thank Mithros – before a cavalcade of King's Own beseeched her. They picked her up, carrying her on her back, restraining her arms and legs so she couldn't hit or kick anyone, and ignored her very audible protests.
The King laughed as fifteen or so members of Third Company carried their heavily pregnant Knight Commander back to her chambers, kicking and screaming in protest.
No one, not even the King's Own Girl could mess with the King's Own Girl.
