I got this idea when I was rewatching the musical episode. The scene with Derek and Meredith in the elevator and she was crying. I thought they finally deserved a baby. Hopefully the writers will get around to that in the actual show soon. But until then I decided to go ahead and write my own version. SO enjoy and tell me what you think!
Don't own Grey's Anatomy!

"DEREK!" Meredith yelled from the bathroom upstairs, "DEREK! DEREK! DEREK!" Derek had been in the kitchen making breakfast when Meredith had started screaming. He dropped the pan on the stove and ran up the stairs as fast as could, worried that Meredith was hurt. He burst into the bathroom. Meredith was standing in the middle of the floor, holding three different pregnancy tests, with quite a few more surrounding her on the counters and floor.

"What is this?" he asked, confused. She thrust one of the tests into is hands,

"Look! Look at what it says!" Derek looked and saw a little pink plus sign on the screen; he smiled a little and looked up at Meredith. "They all say that," she said while nodding. Derek's little smile broke out into a grin.

"You're pregnant?" he asked, his voice full of hope and happiness.

"We're pregnant." Meredith said as Derek pulled her into a hug and held her close. They stayed that way for a few minutes before Derek pulled back.

"How did this happen?" he asked. He was thrilled that twenty pregnancy tests told them that in nine months they would have a baby, but he knew that the chance of them ever conceiving was low.

"I don't know. I don't know. But I don't think we should question it. We don't want to jinx the baby. We need to set up an appointment with the doctor. We have to make sure that this baby will be perfect." Derek agreed and started to walk out of the room, but turned around and walked back toward Meredith. He pulled her into his arms and kissed her passionately,

"We're going to have a baby." They kissed once more then Derek went to finish breakfast and Meredith called the doctor.

The appointment was set for the next week and they were both very nervous about it. They had already decided not to tell anyone until after Meredith got through the first trimester, when she would have less chance of losing the baby. They anxiously went through their week and were greatly relieved when Tuesday came around. They made their way to the doctor's office and signed in. They followed the doctor back to an exam room,

"So Meredith, you told me that you think you are pregnant?" she asked as they each sat down.

"Yeah. I took like twenty pregnancy tests the other morning. They were all positive. Well except for two, but I threw those out."

"Alright, well I'll draw some blood and run the tests and we should know by Thursday if you are pregnant or not." They went through the process of drawing blood and then left the office, slightly disappointed that they wouldn't know right away. They went out to lunch then back to the hospital.

The next two days passed much as the last week had. Derek and Meredith were nervous and on edge the whole time. Finally Thursday came and they were back in the waiting room at the doctor's office. The nurse called them back and they were sitting in the exam room when the doctor walked in with a smile on her face,

"Well Meredith, you are indeed pregnant." She paused a moment, letting Meredith and Derek absorb the news.

"Really?" Meredith asked. The doctor nodded. Meredith turned to Derek,

"We're pregnant!" she hugged Derek who put a hand on her stomach. Meredith looked up at Derek and saw tears in his eyes, "We're going to have a baby."

"This is amazing," Derek said, still slightly in shock. The doctor chose this moment to interrupt,

"We can go ahead and do an ultrasound. It might be too early to see much, but we will probably be able to see the fetus." Derek and Meredith agreed quickly and the doctor set up the machine. Meredith lay back on the table with her shirt up while Derek stood next to her and held her hand. After moving the want around for a moment the doctor stopped in one spot, "Alright, there it is. That's your baby." She pointed out the small spot on the screen that would soon grow into a tiny human.

Meredith and Derek just stared at the screen, mesmerized. After trying for months and months they finally had a baby. Both of them had tears in their eyes as the doctor started talking again,

"Now I want to keep a close eye on you to make sure that the baby is growing correctly and that you are ok. So I want to do bi-weekly visits for the first trimester and then we will see where we can go from there. Sound good?" she asked.

"Sounds perfect." Meredith said. She would go to the doctors every day if it meant that she got a healthy baby.

"Congratulations you guys. I'm happy for you," she said genuinely, before leaving the room. Once again Derek and Meredith embraced in a hug, celebrating their child.

After three months of doctors visits every two weeks Meredith was finally in her second trimester. She had endured mild morning sickness and some low blood pressure, but the doctor assured them that they had nothing to worry about so far. The baby was developing perfectly and seemed to be completely healthy. They had finally decided to tell all of their friends and family this week.

"So how should we tell everyone?" Meredith asked Derek as they lay in bed one morning before they got up.

"Well I was thinking about it. You should probably tell Lexi and Christina first, since they are your sister and best friend. I can tell Mark first. And then we can tell everyone else at the same time. How does that sound?"

"Perfect. Can we tell them today?" she asked hopefully, wanting to share their happy news.

"Whenever you want to."

"Today then," she said, giving him a kiss right before she had to jump out of bed to run to the toilet. Derek followed, holding her hair and rubbing her back as she wretched into the toilet.

"I guess baby doesn't like mommy and daddy kissing." Derek said jokingly.

"Well baby better get used to it. I don't want to throw up every time I kiss you." They continued getting ready for their day and made their way to the hospital. After working for a few hours Meredith finally managed to pull Christina into an empty room.

"What are you doing?" Christina asked, confused, as Meredith pulled her into the empty room. Meredith smiled widely, "Ok, you're kind of scaring me Mer. What's going on?"

"Are you ready to be a godmother?" Meredith asked, letting Christina make the connection herself. After a few seconds Christina's face lit up,

"No way! Really? You're pregnant!" Meredith nodded happily, "Oh my god! That's amazing Meredith! Congratulations!" In a very unChristina like fashion she pulled Meredith into a hug.

"Whoa, we're hugging?" Meredith asked laughingly, a little surprised by the gesture.

"Yeah we're hugging! You're pregnant!"

"I know!"

"Who else knows?" Christina demanded.

"Just Derek. Well, he might have told Mark already. But no one else. I had to tell you first."

"Good. How far along are you?"

"Just entered my second trimester."

"And the baby is healthy?"

"So far so good."

"Boy or girl?"

"We don't know yet."

"Are you going to find out?"

"Maybe?" Meredith said questioningly, "We aren't really sure."

"Well what does it matter, as long as you have a baby right?"

"Exactly!" Once again Christina hugged Meredith,

"Congratulations. You deserve it." She said sincerely.

Meanwhile Derek was sitting in an OR gallery with Mark. They hadn't been able to spend much time together recently since Mark had been busy with his own child. Today they were both on call but oddly had nothing to do. So they sat in the OR of some random surgery catching up.

"Meredith's pregnant," Derek said spontaneously, interrupting whatever Mark had been saying. Mark stopped talking,

"What?" he asked, wondering if he had heard his friend right.

"Meredith's pregnant," Derek repeated.

"Wow. Congratulations Derek! I know how hard you guys have been trying. How far along is she?"

"Four months. And so far the baby and Meredith are both healthy."

"That's great Derek. Congratulations. Now Lanie can have a friend to play with." He said, talking about his daughter.

"They'll be best friends." Derek said as he begun to think about his unborn child's future.

Now that both Christina and Mark had been told Meredith needed to tell Lexie. After looking for a few minutes she finally found Lexie in the cafeteria eating with Avery. "Hey, can I talk to you?" she asked, motioning to the hallway.

"Yeah, sure. Is everything ok?" Lexie asked as she followed Meredith into the hallway. Meredith led her away from any people that may be listening in. "What's wrong?" Lexie asked, getting worried.

"Nothing's wrong. Especially since you are going to be an aunt." Lexie gasped.

"NO WAY!" she squealed loudly as she started to jump up and down. "This is so exciting! Oh my god! This is awesome!" she suddenly pulled Meredith into a hug. "I'm going to be the best Aunt ever! Your kid is going to be so spoiled. Do you know if it's a boy or girl? It's a girl, isn't it? It is, I can feel it. Oh, I am totally going to spoil her so much." Meredith laughed as Lexie started to ramble on about being an Aunt.

"Ok, time to calm down," Meredith said, holding onto Lexies shoulders.

"Sorry. I'm just so excited! Aren't you excited?"

"More than you know." After another round of squealing and rambling Meredith finally left Lexie, who promised not to tell, and found Derek in his office.

"How'd it go?" he asked her, pulling her into his arms.

"Amazingly. How about you?"

"Same. Our kid is going to be well loved."

"And very spoiled." She said, thinking of Lexie. They made their way home for the night and got into bed, before lying next to Meredith, Derek lifted her shirt and pressed his lips to her stomach,

"Good night sweet baby. We love you." He said quietly. Meredith smiled as Derek climbed up the bed and wrapped his arms around her, falling asleep with one of Derek's hands resting protectively on Meredith's stomach.

Alright, so what did you think? I would LOVE reviews for this! Especially because I might continue it. It depends on how much everyone likes it and if I get enough reviews asking me to continue. If I continue it I would probably quickly go through a lot of the pregnancy and everyone's reactions, and then if you guys want, the life of everyone after the baby is born. So tell me what you think so I know if I should continue!
