"You're so big now, huh?" Arizona asked Audrey as the little girl smiled at her.

Audrey was now six months old and her mom and dad were still having trouble juggling her needs and the pressures of their jobs. This day, like many others, Meredith was running late and she still had to drop Audrey off at the daycare.

"She's heavy too," Meredith smiled. "Huh, Baby Girl?"

"Do you want me to take her to the daycare for you?"

"Do you mind?"

"Nope."

"Thanks."

Meredith pressed a kiss into Audrey's dark curls and then handed her and her diaper bag over. There was a little fussing from the baby girl, but it wasn't much. "It's me!" Arizona smiled. "I'm nice! Yeah! And we're gonna go see your daycare buddies!"

"Have a good day, Audrey!" Meredith called after them.

"She will!" Arizona smiled.

On the way to the daycare, they ran into Callie. "Hey," Arizona smiled.

"Do you have a minute?"

"If you walk with me. I've gotta bring her to daycare for Grey."

"Oh."

Audrey's pacifier fell from her mouth as they walked. "Uh oh!" Arizona said. "Mommy and Daddy should get you a clip for that pacifier, huh?"

Callie picked it up and the baby reached for it. "This one's dirty," Callie explained. "We'll look in your bag and see if you have a clean one, 'kay?"

"What did you wanna talk about?" Arizona asked, as she reached into Audrey's bag and found a clean pacifier. "Here," she said as she put it in the little one's mouth.

"It shouldn't take six IUI cycles for a healthy, fertile woman to get pregnant," she said. "I know we keep saying it's just a fluke because nothing ever seemed wrong with my cycle or anything, but I'm really, really sick of this."

"I know," she said.

"I made an appointment with Sterling to talk about our options."

"As in…?"

"Well, IUI has a lower success rate than IVF."

"You're thinking about IVF?"

"I know it's so much more expensive and everything, but I mean, we've done six IUI cycles and got nothing."

"I know."

"So, we're obviously not doing enough," she said, as she fidgeted with Audrey's pacifier.

"Calliope, you get that this isn't your fault, right?" she asked her.

"Logically, yes," she nodded. "But it feels like it is."

"It's not," Arizona insisted. "Really. We'll figure this out and we will have a baby. Promise."

Callie forced a smile.

"When's the appointment with Sterling?"

"Next Friday."

"Great."

Callie had never been so nervous in a doctor's office. Being a doctor, she obviously never minded going to the doctor's. Today though, she was just hoping that their appointment with Dr. Sterling would get them somewhere. Hopefully they'd get some answers or at least come up with a new plan that would have them welcoming a baby into the world relatively soon.

"So, I'm assuming your here because you're concerned that you haven't conceived yet?" he asked when the appointment began.

"Yes," Callie nodded. "Exactly. It's not like I have actual fertility issues. We just can't conceive a baby without fertility treatments."

"Right," he said. "You're ovulating every cycle. Thanks to the Clomid, usually more than one egg."

"I know."

"I'm assuming you want options?"

"Options, tests, whatever you can give me," she said.

"Okay," he said, smiling his most reassuring smile. "We'll schedule you for another appointment so I can check for a blocked fallopian tube."

"What about blood work? Could there be something else going on that's preventing conception?" Arizona asked.

"We'll do some more extensive blood work as well," he nodded. "But her basic blood work that we did earlier seemed completely normal. So I'm not expecting anything there. I know you'd like answers, so I'll do more testing, but that doesn't seem like a likely cause."

"Then what does?" Callie asked.

Obviously the doctor didn't know or he would have just said it. However, Callie was really starting to get frustrated – and a little worried – now. Dr. Sterling was excellent and she wasn't even infertile. Why wasn't this working?

"We'll check for a blocked tube," he said. "And I could be wrong. The blood work could give us some clues."

"If not, what do we do?" Arizona asked.

"We have a few options," he reassured them. "For starters, we could increase the dosage of Clomid. If you ovulate more eggs, there's a higher chance of conception."

"And also a higher chance of multiples," Arizona pointed out. "We want this to work, but we don't want this to work too well."

"At this point, I just want it to work," Callie said. "Multiples or not."

"Me too," she agreed. "But many multiple pregnancies are so complicated."

"I know," she said. "It's not ideal."

"Exactly," Dr. Sterling said. "But it's a choice."

"What about IVF?" Callie wondered.

"IVF could be a very good option for you if it's a matter of the sperm just not fertilizing the egg. As long as we don't find any problems with your eggs, that could certainly be a great way to go. If we fertilize the embryos and then implant them, there's a higher likelihood of success."

"Yeah."

"But IVF is also much, much more involved than IUI is."

"We know," Arizona said.

That was one of the reasons they had decided to try IUI first. IVF carried with it more steps, more risks, and a higher price tag. Money wasn't the only concern, but there was a difference between paying a few hundred dollars per attempt or paying multiple thousands of dollars per attempt. It was something to think about for sure.

"So let's do the blood work and book you for another appointment so that we can look at your tubes," he said. "We'll start there and hopefully we have answers soon."

"Thank you," Callie said. "I'm sorry to be freaking out, but –"

"I'm a fertility specialist. Almost all of my patients are a little anxious. Especially after more than a few attempts. I understand completely."

"Good," she smiled.

"And I know what it's like."

"You do?"

"My wife and I were diagnosed with unexplained infertility. Which basically isn't even a diagnosis. And the irony or helping couples conceive every day and not being able to get my wife pregnant was just…"

"So what did you do?"

"Everything under the sun," he nodded. "And…still nothing."

"Oh," Arizona replied.

"I'm probably one of the only fertility specialists who gave up and adopted, but after a while it seemed like the best choice."

"Your kids are adopted?" Callie asked.

"It's not exactly something I love to share with my patients," he admitted. "Not that I'm ashamedof them or anything. Just…patient's start doubting me. If they know that I couldn't even solve my own problem."

"It's not like it's your fault," Arizona said.

"I know, but some people don't exactly see it that way. And I just want them to have confidence in me as a doctor."

"No worries here," Callie said. "We do. For sure."

"Thanks," he smiled.

"Can we afford IVF?" Callie asked Arizona as they lay in bed later that night. "If it comes down to that."

"Of course," Arizona said. "It'll probably mean making some sacrifices, but yeah. I mean, we aren't paid as well as some people at work are, but it's not like we're struggling."

"Yeah."

"See, Shepherd can do clinical trials until the cows come home," she said. "And get published. All that good stuff. Which makes the hospital look better and ends with a bigger paycheque for him. In Peds, that's not how it goes. The FDA hardly ever approves anything. Even if they do, parents aren't exactly lining up to subject their children to God knows what. Nobody should be playing Russian Roulette with the lives of the tiny humans."

"No," Callie said.

"But yes," she answered. "If we have to do IVF, we will."

"Okay."

"But let's just wait and see what Sterling says once we get all your results."

"I hate to even think about this," Callie said. "Because I really, really wanna be pregnant, and you really, really don't. But if I can't, would you…?"

Arizona kissed her. "Let's cross that bridge when we come to it, 'kay?"

"I'm sick of waiting."

"Our baby is gonna be so, so, so worth it, Calliope."
