Do not worry about the door. Unless you had a flash that could compensate for the indoor setting, and the sky peeking through the door, don't sweat it. In future though, try to minimize (if its your intent), light you cant control:
Position yourself so the womans head is blocking the light from the sun.
Shut the door.
Use a dedicated flash to light your subject, while exposing for the harsh light (so that both the lightsource and your subject will be properly exposed).
