Castle was sitting at his desk attempting to get some work done, but as usual he was completely distracted. It started out as taking notes on the case they had just closed, but ended up being nothing more than messing around on the internet. He was relieved when he heard the front door shut. If Kate was home, he could call it a night and give up completely on work.

"I'll be right out," he called from his office as he saved and shut down his laptop.

There was no answer, but he didn't think much of it and headed to the living room. Kate was standing just inside the door and appeared to be completely frozen in place. She looked as if she was about to just crumble to the floor.

"Honey?" Castle had no idea what could have happened. When he left the precinct to let her finish the paper work all was well. They caught the killer, and everything was fine.

She still didn't respond but simply took a few steps towards him. She stopped suddenly and stared at the floor. Rick closed the gap between them, and she practically flew into his arms. He quickly pulled her close and encompassed her in his embrace. Neither one of them said anything and just held each other for a long moment.

Finally, Castle took a deep breath and asked, "What happened?"

Once again Kate didn't say a word, only slightly shook her head. He squeezed her tight and gently pushed her back so he could see her face, but she stayed latched on to his forearm refusing to break contact.

"Let's sit," he said guiding her to the couch.

"I lied the other day. When I told you I was going to meet my dad for lunch, I lied," Kate finally spoke up.

"Ok," he said questioningly.

"I went to the doctor's."

"Kate, I need you tell me what's going on." Castle went from worried to completely panicked.

"I thought I was... well I was. I wanted to be sure before I told you. I had this whole thing planned out in my head. I was going to top your proposal. You would have loved it."

"Loved what?" He asked out on breath.

"I thought I was pregnant," She nearly whispered.

He didn't say anything just pulled her over the small space that was between them and into his lap, wrapping his arms around her. He leaned back against the couch, and she leaned against his chest. After about 5 minutes, she pulled it together and was able to explain what happened.

"I took 3 tests. They were all positive."

He squeezed her shoulder wordlessly trying to be strong for her.

"I wanted to tell you right away, but I wanted it to be special. I didn't want to just run into the room and yell 'I'm pregnant," She explained."So I made an appointment and came up with a story."

"Lunch with your dad. Good cover," he said with a smile.

"I was so nervous when you asked if I wanted you to come."

"Come to think of it, you did seem a little twitchy."

"I'm not so great at lying to you," she admitted.

"I can't say I'm complaining about that," Castle said with a laugh.

"I answered all the doctor's questions, and she took blood. It all seem good."

"But?" He asked rubbing his hands up and down her arms soothingly.

"When she called the next day, she said my hCG levels were high enough to indicate I was pregnant but lower than normal at this stage," Kate explained.

"What does that mean?"

"She said to try not to worry about it, and I would have to come back for another blood test."

"Ok"

" So I went back yesterday, and she called just now when I was leaving the precinct... It was even lower."

"So you're not pregnant?" Rick asked confused.

"I had a miscarriage. I wasn't... I wasn't far enough along for any of the normal signs or symptoms."

He just sat there in complete shock. He had no idea what to say. He didn't even know what he was thinking. All he knew is that he hurt, so he held her a little tighter and tried to work through it.

"They... They can be sure? Just from a blood test?" He stuttered out after a moment.

"I wasn't far enough along for an ultrasound or anything. We only caught it at all because of when I had the test. Supposedly this kind of thing happens a lot for all kinds of reasons."

"I'm so sorry," He offered kissing the top of her head.

"For what? If anything I should apologize."

"Kate, No! This is not your fault," he immediately said turning her so they were facing each other.

"I know," she practically whispered. "I didn't tell you after the first test because I still had hope it would all be ok."

"It will one day. We'll try again."

"I'm 34, Rick."

"So? We have time." He reached out and took both her hands in his.

"Not a lot."

"We don't need a lot."

"Yeah, but..."

"But what?" Castle pushed. He had stopped letting her back down a long time ago.

"It's just... I don't know."

"You are by no means too old to have a child. Not at all."

"I know. I just wish the doctor could tell me why this happened."

"She can't? Maybe she could do more tests."

"She said that this happens in the beginning stages of pregnancy a lot more than people know. Most women don't even realize that it happened. They don't know they were pregnant at all."

"But you knew?" Castle smiled.

"I downloaded that stupid app. The one that tracks your periods and ovulation schedule. It lets you know right away if you're late."

"I thought you were joking. That's a real thing?"

"It's on my iPad," she laughed as he reached for her phone on coffee table.

"I guess there really is an app for everything."

"I'm impressed it worked."

"I don't know if I'm impressed or freaked out."

"It is kind of strange," she shrugged.

"Are you okay? I mean physically," he blurted out. The thought suddenly dawning on him.

"Yeah, I'm fine. I didn't... I didn't really feel anything," she said finally letting tears fall. Despite everything they have been through and how far they've come, she still hated crying in front of him.

"I promise, Kate. One way or another we are going to be parents," he whispered reaching up to wipe her cheek.

"I love you."

"Love you too. So much, Kate, so much."

So I got this idea in my genetics class the other day. I'm nerd who seems to think Castle and Beckett going to a genetic counselor and trying to have a baby would be fun to write. Yeah, not so much fun as heart breaking. I'm not sure why I chose this as my starting line. Any one who has read anything else I've written knows I'm an awful updater. My apologies again. Any and all medical information is based off a combo of class notes, Google, and Grey's Anatomy. I'm an undergrad premed student. I would love to hear what you thought of this story. Reviews are awesome. Feel free to share all opinions and thoughts good and bad.

Thanks for reading,

Meagan

Better late than never: I don't own Castle in any way, shape, or form except in my dreams.
