You were pregnant, and since you were part of the team and you had information about everything and the base, the team decided to keep you under security and keep you here, at the base. (You can decide if the father is someone in the team or just someone random you can add)

So here you were, at 40 weeks, walking around in circle and muttering ‘’Open that pelvis, we gotta open that pelvis’’ at 3 in the morning, Nobody knew who the father was due to you, and the father not telling anybody.
