This one is for my lovely Chicago PD Secret Santa recipient upsteadhc for the prompt: "any prompt from an angst or fluff list" so I figured what's better than an Upstead pregnancy oneshot. A little bit of angst, a little bit of fluff, I hope you enjoy it! Merry Christmas and a Happy Holiday Season!

For Better of For Worse, Even When Pregnant

Hailey glanced at their front from her spot on the couch in their dimly lit living room before checking the time on her phone for what felt like the hundredth time. At reading the numbers that read 1:28 AM plastered over her background that was a photo of her and Jay from their gender reveal party a few months ago, she sighed and took another sip from her now semi-cold tea. Fighting the urge to close her eyes with each passing moment, she'd been hoping for a voice mail, a quick text, something, anything that would give her enough relief so she could at least attempt to sleep, but there was nothing, and the wait was driving her crazy. Since their last call, there was an uncomfortable feeling eating at her insides, something in the pit of her stomach that had been growing for a few days, and she knew it wasn't just her nerves growing from being only a week away from her due date. She'd gotten this same feeling a few times in the past few years, and she prayed to God that this time wasn't like those other times. Where the hell are you, Jay?

The unit had caught a big case a week ago: a dead pregnant girl that led the team to an international human and child trafficking ring smuggling young girls from all around the world into the States, forcing them to get pregnant, and selling the babies to God knows what kind of people. It was an understatement to say it was a rough case, even for Intelligence's standards, and from the limited information Hailey knew about it from her lunch dates with Jay at the precinct, and the occasional calls and visits from Kim and Vanessa so Hailey wouldn't actually lose her mind staying at home, it wasn't going to be a walk in the park to solve.

On a regular night, Hailey wouldn't worry about Jay staying late to go over evidence or to work on paperwork, especially while they were working a new case, but this time felt different. She couldn't put her finger on it, but there was something about the way Jay had been especially quiet at home the past few days, those days that he had actually made it home before Hailey went to bed. It was almost as if he had been trying to avoid her, and successfully so. Then there were his texts: one word answers after taking forever to respond, that was if he responded. It wasn't like she was expecting immediate responses or constant texting either. She knew that whenever a big case, especially something this big hit, it was all hands on deck with no room for distraction, but she at least expected a response, any response, when she asked if he'd be coming home for dinner, or if he was okay.

Now, having been partners with Jay for seven years, dated for two of those and married for one, Hailey could tell when a case, or someone, was irking him. So when he had started acting a little off the first time, she had given it to the combination of the caseload and having to work with a new partner now that she was officially on maternity leave, and done with desk duty, as per Voight and Platt's orders. Jay'd been looking to find something to complain about his new partner from the day Voight had brought in Detective Aiden Thomas, a freshly minted detective from narcotics, as Hailey's temporary replacement. Whether it was the way the young detective tabbed evidence files or the way he sipped his coffee during stakeouts, Jay found an excuse to text her, whining about being stuck with the new kid. So when the texts got more staggered and eventually stopped, Hailey had started getting suspicious and when she hit absolute radio silence the entire day that day, with no luck during the night either, Hailey knew it was time to call in back-up.

Around 10:00pm or so, Will had been the first person on her call list, not wanting to alert anyone on the team just yet if the older Halstead could reassure her enough to get that sleep she oh so craved. It also helped that she knew that Will was on call that night, him having shared his work schedule with Hailey since she was so close to her due date and who knew where Jay would be if she went into labor. Unlike his younger brother, Will had picked up Hailey's call in two short rings. "Hailey? What's up? Are you okay? Is it the baby?" He had asked in doctor mode.

"Yea, we're good. I was calling to see if you heard anything from Jay today?"

"Jay? He was here this morning to talk to an injured suspect but that's about it."

"Did you realize anything off with him?"

"Not that I could tell. He and his new partner were in and out. I didn't even see them leaving." Hailey sighed in defeat at her brother-in-law's response. She had really hoped he would say something that would ease her growing nerves. "Hey, is everything okay?"

"Yea, yea things are fine." Hailey took a deep breath. "I just haven't heard from him the whole day and he hasn't come home yet and…" Her voice trailed off as her words died.

"I can-"

"No, that's alright." She cut him off, turning down his offer. "I don't want him to worry if they are working."

"You sure?"

"Yea, knowing Jay, he'll think I'm in labor or something and freak out." She attempted at a joke to hide her worry.

"You know, it would teach him not to ignore his pregnant wife." That even earned a soft chuckle from Hailey.

"Thanks, Will. It's not even that late, I'm sure it's just me being paranoid." She tried brushing it off. "You know how much I love staying home all day."

"Don't I know it?" Will went along even though he knew that for Hailey to be calling him, she must have a good reason to worry. "You and Jay are the worst people at enjoying doing nothing."

"Yea, I'm ready to go back to work once your niece finally graces us with her presence." She told him, her hands instinctively rubbing her 38, almost 39, week along belly at the thought of finally getting to meet her baby.

"I'd be careful wishing on that this close to your due date, Hailey. It might happen any day now." He jokingly warned her, hoping he was providing some comfort with this distraction.

"I think it's safe to say when it happens, you'll be one of the first ones to know. I guess the first one to know if it happens during this call." Hailey responded, though the only thing she could think of as silence fell was what she'd do if she were to go into labor now and Jay was nowhere to be found.

"Regardless, you know I'm here if you need me." Will broke the silence.

"Thanks, Will. I'll let you get back to work."

"Alright, but seriously, call me if you need anything. I'll be up all night."

"I will. Thanks, again. Good luck with your shift."

"Any time. Now stop worrying about that knucklehead and try to get some sleep." Will jokingly ordered and with a mumble of agreement, Hailey hung up. Sleep… She really hoped she'd be able to get a little bit of it that night.

She'd given him about an hour after calling Will, called and texted a few times, but when those had gone unanswered once again, she'd moved to the next person on her list and called Kim, really hoping that they were really just working late and she wasn't waking her up. "Hey, Hails, everything okay?" Like Will, Kim picked up the call in a few rings. It was almost as if everyone who knew Hailey was on call to answer her calls except for her husband.

"Hey, sorry I'm calling so late. Am I interrupting anything?"

"No, no, actually Kev just came back from a coffee run so I was taking a break." Kim answered, followed by a yawn.

"Case wearing you down?"

"It's a bad one. We found two of our suspects, who of course didn't go down without a fight. One of them took a bullet to the knee so we are waiting for Med to release him into our custody when he's done and the other's downstairs." Another yawn. "But looks like it's gonna be a rough night. Well, I guess morning."

"Everyone okay?" Hailey asked after hearing that their suspect had put up a fight. If he had gotten shot, it meant that he had started the shooting, and her heart started racing thinking all the worst case scenarios. Surely she would have been notified if something serious had happened to Jay, but with the way he had been so distant lately, maybe that had been it: he had gotten injured and was avoiding her calls.

"Everyone's good, came out without a scratch." Hailey released the breath she hadn't realized she'd been holding. "Hey, is everything okay with you?" Kim asked upon hearing Hailey's loud exhale of breath. "Oh my god are you in labor?"

"No, everything's good here. No baby just yet." She answered quickly, getting that out of the way. "I was calling to see if Jay's around. I've tried calling him a few times but his phone kept going to voicemail, but I guess you guys are busy so I'll let you go."

"Ummm, Hails, Jay left a while ago."

"Oh?" Kim's answer took Hailey by surprise, an unpleasant one. She lost her train of thoughts and stuttered as she tried finding the words to ask her next question. "Did he- umm, did he say where he was going?"

"No, sorry. We all figured he was gonna go home and get some sleep. It's been a rough day for him."

"What happened? Is he okay?" It felt weird to not know that Jay'd had a rough day. It felt weird being the one to ask what was happening with him.

"One of the suspects we caught turned out to be ex-military. Someone Jay knew back in the day." Kim told her. "I think Jay was hoping the lead would turn out to be bogus since his name came up a few days ago but…" The rest was obvious. Finding out an old buddy involved in such a disgusting case must have taken a toll on him, and understandably so. What Hailey couldn't figure out was why he hadn't talked to her about it, and the question hurt her more than she thought it would. "Jay must have gone on a drive or something. I'm sure he's on his way home though."

"Yea, yea, you're right. I've probably just been losing my mind from having to stay home." She tried laughing it off again, just like she had done it with Will, but this new found

"Oh, tell me about it! A few days is enough to drive you insane." Kim commented, as bittersweet it was, remembering having to stay back during her short lived pregnancy so many years ago.

"Oh yea." Hailey tried acting her usual chipper self but the fake smile plastered on her face failed to reach her voice. "Anyway, I should let you enjoy your break."

"You sure everything's okay?"

"Yea, yea, everything's fine. I'm getting pretty tired anyway and you guys are busy." She added a fake yawn to her sentence which made Kim yawn as well. "Thanks for the conversation."

"You want one of us to drop by? I know Kevin's about to head home for a quick nap and-"

"No, that's fine." Hailey cut her friend off before she could finish the sentence. "It's pretty late."

"Alright, well Adam, V and I are gonna be staying here tonight if you need anything. Just give us a call, alright?"

"Thanks, Kim. I really appreciate it. Enjoy your break and good luck!"

"Good night, Hails." The line went dead, leaving Hailey to her thoughts, wondering where her husband was, worst case scenarios running through her head. The last time he had gone awol, he'd gotten kidnapped, shot and almost died. She couldn't go through that again. Not now. Not when they were about to have it all. With tears in her eyes, Hailey swore he would never forgive Jay if he left them alone.

About another hour or so later, the clock almost hitting three in the morning, Hailey was just about ready to give up, go to bed. She was exhausted, achy, and really, all she wanted was to know that Jay was safe. They could deal with this, whatever it was, in the morning. Hell she didn't even care if it meant that he'd continue avoiding her, and she'd have to wobble to the precinct in her pajamas. That being said, she knew sleep was her enemy tonight and the moment she would decide to go to bed, the oh so tempting sleep that had been trying to pull her into dreamland would disappear the moment her head'd hit the pillow. Not that sleep was really an option with their daughter kicking up a storm in her belly either.

"It's okay, munchkin." Hailey rubbed the spot she kept feeling the kicks. "It's all gonna be okay." Realizing she had no tea left, she threw her blankets off and stood up to stretch. If she was going to stay up, she needed to keep herself otherwise occupied. "Let's get mommy some tea and you some of those cookies you crave so much."

Hailey was about to head to the kitchen to get herself another cup of tea and get a snack when the sound of the door opening startled her. Her head instinctively turned towards the source of the noise, and watched frozen as Jay's silent silhouette moved in the foyer. She held her breath as her eyes followed his every move: The way he snuck into his own house, the way he took his jacket and shoes off as quietly as possible, thinking Hailey was already asleep, the way he tiptoed further into the dark house. Watching his arm reach for living room light switch, Hailey prepared herself to face their current situation, and when the lights turned on, bringing the couple face to face, a loud silence surrounded them. "Hails? Why are you awake? Everything okay? Is it the baby?" Jay listed his questions, alarmed.

"Yea, yea we are fine but I guess I should be the one asking you that." Hailey shot back, needing him to know that what happened today was NOT okay. "What's going on, Jay?"

"Nothing, nothing. I'm fine." He gave her his staple bullshit of an answer as he walked further in and towards her in the living room. "Just a long day at work."

"Well, I know for a fact you're not "fine", so wanna try again?" Hailey crossed her arms over her chest, her words stopping him on his tracks to walk over to greet her.

"I-" He started but seemed to be at a loss of words.

"Jay, I'm worried about you." She cut him off at the realization that he needed a push before he'd really open up. "You haven't picked up your phone or answered any of my texts and I had to find out from Kim that you had a rough day. What's going on?"

"Hails, I'm just really tired and just want to go to sleep." He was hiding behind an excuse, but at least it was an honest one, and Hailey considered that a good start.

"Alright, if that's what you want, we can go to bed. I'm glad you're safely home." She told him with a flat yet soft tone. She didn't want to discourage him from opening up, but his actions had terrified and hurt her, and she couldn't just pretend that it was all fine now that he was home. "But we are gonna talk about this, Jay." She added, letting him know he wasn't off the hook. "What happened today, the radio silence… The last time that happened, I almost lost you and the thought of losing you, especially while I can't even be out there," The memory of what Angela Nelson put them through hitting her straight in the pregnancy hormones and feelings, she could feel tears welling in her eyes, but she wouldn't cry. She refused to. "It, it terrified me," She looked down her body in an attempt to avoid his eyes and blink away the tears as she protectively put both her hands on her bulging belly. "It terrified us." She sighed. "We, we have to talk about it."

"I can't do anything right, can I?" Jay muttered more to himself than Hailey, disappointed in himself. He knew he was in the wrong. He knew he shouldn't have pushed Hailey away, but this case, these past few days, then what happened in the morning… It had brought up so many painful memories, so much rage, so much fear that he simply hadn't known where to start. "You must hate me for what I put you through today, huh?"

"I don't hate you, Jay. I will never hate you." Hailey's voice softened. "But I hate that after all this, you're still trying to lie to me."

"Hails…"

"Yes, Jay?"

"This case has been terrifying." He started to confess. "When we found that pregnant girl, the way her body was left behind, all I could think of was you and what I would do if I found you like that." He was finally opening up. "Then we found out that one of the suspects is an old army buddy of mine and when we interviewed him today…" He shook his head, the memory of the interrogation room replaying in his mind and he collapsed on the couch in defeat. "He looked me in the eyes and said "You'd make pretty babies. Should consider changing careers." with the smuggest smile, and Hailey, the things I wanted to do to him for bringing our kid into it… And then all my anger turned into this fear of failing you and Aislyn and, God, Hailey, it paralyzed me. I couldn't think of anything else."

"Jay," She got it. She really did, but the silence and distance had hurt. "Holding everything in doesn't help you know." She told him as she walked over to take a seat next to him and put a supportive hand on his back. "Why didn't you tell me what was happening?"

"I know I should have." He looked at her with tear sheathed eyes, his greens tired and broken. "I mean I know I could have come to you. I trust you more than I ever trust myself, but I didn't want to worry you especially with how close you are to your due date. It felt like by burdening you with my worries, I'd be failing you two before we even became parents."

"I understand, Jay, but not knowing what was going on with you and having to call our friends and family only to find out from Kim that you've been having a rough time with this case worried me so much. I felt like an outsider and not your wife and best friend." She took a deep breath, giving Jay some time to process her words. "Your worries and fears and rage will never be a burden on me, Jay. We said for better or for worse when we said I do. Being pregnant doesn't change that."

"God, I love you and I'm so damn sorry." Jay pulled Hailey into his body and apologized with a broken voice upon realizing how much he had hurt her. The last thing he wanted to do had been to hurt her, but he realized trying to not be a burden was more hurtful to their partnership than anything. "I promise I'll do better."

"I know you will." Hailey snuggled into his embrace before turning in his arms to be able to look him in the eyes again. "I love you, Jay." She cupped his cheek in her one hand, and grabbed and guided his hand to rest over her belly with her other. "We love you. Unconditionally. Just remember that the next time you feel overwhelmed and I'm not there." Feeling their daughter's kicks under their palms, Jay leaned down to press a kiss on her lips; a kiss meant to seal his promise, to show his love, to give them both hope that they were stronger for facing their challenges.

Their last few days had really taken a toll on both of them, but with everything out in the open now, and promises of love and hope had been made, they knew they could tackle anything as long as they trusted in each other, even when they didn't trust themselves.

So when they finally got into bed, tightly holding one another close, their daughter's soft movements between them, they finally got the relieved rest they had been needing that day.

Merry Christmas, everyone!
