Can I request to separate due to pregnancy?
Pregnant servicewomen may request separation due to pregnancy. Requests are normally denied, unless it is determined to be in the best interest of the Navy or if the member demonstrates overriding and compelling factors of personal need which warrant separation. Refer to MILPERSMAN 1910-112 (enlisted) MILPERSMAN 1920-180 (officer).
