Y/N was able to conceal a pregnancy for 9 fucking months without anyone questioning her. She got pregnant and then hid it because she hated that her husband divorced her because she was pregnant and didn't want to continue having sexual nights while pregnant. 9 fucking months she continued working, she contacted to hide her pregnancy (great at it, she controlled morning sickness without a reaction, smells didn't bother her, she hid pain well, etc.) But then after 9 long months it happened. Y/N was at home, waiting for Gibbs to arrive because he was wanting to discuss stuff that were unrelated to the case. While waiting, y/n went into labor. Not water break and contractions every once and a while. It was water break and strong contractions ever minute. When Gibbs arrived y/n was sitting down, she hurt to much to move. Gibbs didn't know anything about the pregnancy or y/n being in labor.
