A/N

Hey guys! I finally got around to publishing this story. It's been on my mind for so long, and I'm glad I'm finally sharing it! Please R/R, and I really hope you enjoy!

...

Robin ran through the halls of WWN dodging people until she made it to her office. She ran into her private bathroom, locking the door and groaning and vomiting into the toilet. When she was done, she sat against the wall breathing heavily. This had been happening for weeks. She thought for a minute. What was wrong with her? Barney was getting worried. He had tried to get her to stay home today but she didn't want to. She insisted on coming into the office. Robin wasn't a weak person and being sick wasn't going to stop her from working no matter how much her husband insisted she stay home. She got his point though, she had been awake at crazy hours of the morning in the bathroom puking which kept him awake because he couldn't sleep when she was sick. Barney was always beside her to comfort her.

Ten minutes later, Lily came into Robin's office so the two could go out to lunch. She was late, as usual, because The Captain always had just one more painting to show her. But at least she was there.

"Hey, so Robin guess what. The Captain just sold a painting we…Robin?" Lily stopped talking when she realized her friend wasn't at her desk.

At the sound of her friend's voice, Robin got off the ground and quickly flushed the toilet. She stood in front of the mirror and quickly touched up her lipstick before opening the door and greeting her friend.

"What's wrong?" Lily seemed concerned.

"Nothing." She replied. Lily raised her eyebrows unbelievingly. Robin sighed. There was no getting past Lily and her stupid mother's intuition. "I've been sick for weeks. Vomiting, headaches, back pain. That kind of stuff."

"What else?" Lily asked, diving straight into mom mode.

"I don't know, insane cravings, I guess. That's not unusual though."

Lily bit her lip. "It sounds like you're pregnant."

"Lil, that's impossible. You know I can't have kids."

"I know but maybe they got it wrong. What you're experiencing is pretty common symptoms for pregnancy."

Robin shook her head. Lily wasn't making sense. Why was she bringing pregnancy up? It was a little cruel to tell an infertile woman that she might be pregnant. There was no way she was having a kid. "These aren't uncommon. It's probably all symptoms for some most types of cancer and incurable diseases, too."

"Robin, don't joke about that. I'll get you a test, but you need to find out."

She put her hands up, surrendering. "Okay, okay. I'll get one on the way home today. I promise."

During lunch, Robin couldn't stop thinking about it. Was Lily right? She knew what the doctor had said, but maybe that was wrong? Realizing that it was a possibility hit her like a ton of bricks. She picked at her food in the takeaway container and looked across the table at her friend. "Suppose I am pregnant, how do I tell Barney?"

"Don't worry about him. It's Barney. He'll be happy because he loves you so much. And, he would love a kid too. He knows what it's like, growing up without a dad, and he would never let that happen to his own baby."

"True." What Lily said made sense, but Robin couldn't help the thought as it kept clawing at the back of her mind. Would he still love and want to support her when she was throwing up from morning sickness? Or when the mood swings started? She tried to block out the negative thoughts but they wouldn't go away.

"Are you okay with this? I know kids weren't part of your plan."

Robin bit her lip. "Actually, I don't think having a baby would be that bad. Barney and I are in a loving relationship, and I'm at a stable place in my career. Maybe it would be a good thing, and I think it's time to take the next step in our relationship. As long as he's okay with this. I think I'm ready." Robin replied.

Lily grinned. "I really, really hope I'm right!"

After a quick detour to the pharmacy to pick up a test, Robin got in a cab home. She started to really think about it. About some of the things Barney has said before. Such as one of his vows: I vow to love you forever unconditionally, unless you pudge out. In which case, I'm a Barney-shaped hole in the wall. What the hell was he going to think when he knew she was going to pudge out big time?

The realization that she was probably pregnant hit her at full force and the tears got the better of her and flooded out. She didn't need a bit of plastic to tell her she was having a baby. Deep down, she already knew. Robin got out of the taxi at her and Barney's apartment and pawed at the mascara running down her face in a vain attempt to look less like she'd just sobbed her heart out. She opened the door to the apartment silently praying to be the first one home. She wasn't. Barney was standing in the kitchen on the phone to Ted.

He looked up and smiled at her, then his expression turned worried as he saw her tears. He cocked his head, silently asking her what was wrong. "Ted, I'll call you back later. Robin's upset." He hung up the phone and walked over to her, pulling her closer to him. "Babe, what's wrong?" He sounded concerned, and it made her feel worse.

She struggled trying to think of what to say. "I…um…" Instead of trying to explain herself, she placed the box containing the pregnancy test into his hands.

Barney's eyes widened and he was speechless. This was so unexpected. "Oh…woah."

Robin's lip quivered. "I'm supposed to be infertile. I know you probably don't want this-"

He cut her off, knowing he had to be the voice of reason. "Hey, stop it. Nobody said I don't want this. I love you. Start by taking the test. Come here."

He pulled her towards the bathroom, and sat on the bathtub, handing her the stick and reading the instructions. It was simple. "Just pee on the stick, we wait two minutes, see if there's a plus or minus sign." He explained.

She did as he said, then sat beside him on the edge of the bathtub with the plastic stick in her hand. Her eyes were closed and she was counting quietly. When two minutes came, she opened her eyes but couldn't will herself to look at it.

She shoved it into her husband's hand. "I can't look. I'm too scared."

Robin read his expressions as Barney turned it over and glanced at the little window. He did a double take, then grabbed the box, double checking that he was seeing the right thing. He looked up at her in awe, then dropped the test to the floor and pulled her into a hug.

"It's positive, Robin. It's positive. We're having a baby. Oh my god, I'm going to be a daddy!" Barney said. He was excited, but holy crap he was going to be a father. Robin was going to be a mother. A child was growing inside her stomach. His child. His child, that felt strange to think but it also felt right in a weird way. He was going to be a daddy!

"We're having a baby." She repeated. "Are you okay with this?"

"Of course I am. I love you. I couldn't imagine anyone better to start a family with."

She took a deep breath before speaking again. He wasn't thinking properly. She knew he was thinking of the cute things, and not about all the poop and vomit. "We're talking about a lifetime of commitment. Are you sure you'll want to be here when I get massively fat and gross and all I want to do is watch reality TV shows and sleep all day? When I don't make it to the bathroom in time and puke all over you. When I'm sweating and grunting during birth. When the baby's crying at 2 am and we can't figure out what's wrong?"

"Yes, babe. I promise. I don't care about the cravings and the mood swings or the pregnancy brain. I don't care about any of that, because you'll be forming and carrying a baby. That's awesome. And for god's sake why do you think I'd care if my pregnant wife was fat? That's the whole point, stupid." He grinned as he teased her. "Besides, if I let you raise a kid on your own then he or she would only be a little awesome. And you'd probably tell him or her that they're completely Canadian." Barney shuddered at the word Canadian.

"I mean, the kid would have more Canadian blood than American."

Barney shook his head. "Poor kid."

Robin laughed and shoved his shoulder gently. He smiled. Getting her to laugh always made him happy.
