Robb Stark!

You were in front of the mirror in your room, looking for the loosest dress you could have to cover your small belly that was beginning to protrude with the passing of the months.

'It had only been a couple of nights,' you told yourself, thinking of the nights you had shared a bed with the King of the North.

The wooden door creaked, warning that someone was entering the room. Robb's eyes scanned you and settled on your small three-moon belly.

What does this mean?
