She managed to get to the bed and when she finally could sit down her worst fear came true she felt something moving inside her. She let out a loud scream that made Jon runs upstairs when he didn't even knock on Sansa's door he just entered and asked her "What wrong?" Sansa with a worry and devastating face say "I AM PREGNANT!"
