Meredith sat hunched on the toilet with her arms wrapped around her midsection. She could see the box of tampons sticking out of the cabinet, but she'd rather wallow in her misery and ignore the fact that her uterus was slowly dying and it hurt like hell. She thanked her lucky stars she and Derek had the day off. A soft knock at the door pulled her from her thoughts.

"Mer? You okay?" Derek called from the other side of the door.

"Yeah I'll be done in a minute." She replied, reaching for a tampon. Meredith finished her business and washed her hands, her uterus complaining at every slight movement. She practically collapsed in Derek's concerned arms when she opened the door. His hands find her lower back and she practically melts into him as he takes some of the pressure off her back.

"You okay?" Derek asked into her hair and all Meredith can do is moan in response. "Come on." He whispered guiding her back to their bed. He helped her into bed, he ping steady pressure on her back. He tucked her in before disappearing. She can hear him banging around in the bathroom, but she's to miserable to care. She does off and when she woke up next, Derek was placing a heating pad over her midsection.

"You know sometimes, I appreciate the fact that you have four sisters. I don't really like that I have to meet them all but the fact that periods don't freak you out is nice." Derek chuckled from behind her. His hands run up her back gently and Meredith can feel herself relaxing.

"You know," Derek whispered "when I imagined spending the day in bed, this isn't exactly what I had in mind."

"I'll make it up to you in 5 to 7 days, promise" Meredith smiled. Derek nuzzled into the back of her neck.

"I love you."

"I love you too."
