A/N- Hey guys, sorry it took so long to update! So here's this chapter for y'all before tonights episode! Loved all the reviews, they make me so happy and brighten up my day!

The next morning Jay woke up and looked over, beside him was Erin laying on her back, her belly making the blanket hug her pregnant form. Jay smiled and scooted closer, he kisses her shoulder then her cheek. Her eyes open slightly and she smiles when he lays his head in the crook of her neck. He places his hand on her belly and just lets it rest there for a little bit.

"I know it's a little early but got any names in mind?" Jay wonders.

"You know, I honestly haven't even thought about that yet. You?" Jay looks at the ceiling before shaking his head.

"Not really, I figured i'd pick up a book after next shift."

"Why get a book when we can just use the internet? It'll save us some money that we could use to buy clothes or something" Erin says as she sits up and reaches for her phone.

"True... So, we have the day off. What do you wanna do?" Jay asks, getting off the bed and pulling Erin by her ankles to the end of the bed. She lets out a laugh and kicks her legs a little bit.

"Finish the room maybe?" Jay suggests.

"How about one of those birthing technique classes where the father goes and tries not to piss the teacher off?" Erin smirks, holding up her phone and the calender, she actually had called ahead of time and got a spot in the class.

"Anything for you dear" Jay says sarcastically and flashes a sarcastic smile.

"Oh come on, it'll be fun! Please? I'll let you drive" Jay smirks as he looks at her.

"Really?"

"No, c'mon it starts at 1, I want a juicy burger, pancakes, cookies and strawberry ice cream. Oh and some taco salad!" Erin says energetically and eagerly goes into the bathroom to put her hair up in a messy bun then grab some maternity athletic clothes from her dresser. Jay smiles, he stifles a laugh at how happy she was acting. He can't deny the fact that he loves a pregnant Erin, even with the hormones manipulating her mood.

"So, what did you want for breakfast?"

"sausage, egg and cheese muffin sandwich. But I wanna cook it, I haven't cooked a meal in-"

"Never?" Jay interrupts. He shields his face as Erin hits him with her yoga pants.

"fine Chef Halstead, prepare me the greasiest sandwich you can. Don't worry I've been grocery shopping, I need to eat so much lately. I crave the weirdest stuff" Erin continues to ramble on while Jay prepares her breakfast. He doesn't see this side of Erin much but he loves it and finds it adorable.

"And deep breath in, imagine yourself in a place you can relax. Good, very good."

"Daddy's, I want you to place your hands on mommy's belly and rub in circles as she leans back onto you, feel a connection. Remember to relax" The woman's soothing voice says.

Erin leans back into Jay as he rubs her belly like the lady instructed, Erin smiled to herself and closed her eyes. After some more exercises the class took a small break, a lot of the mothers talked with each other, Erin and Jay stuck by each other and waited for the break to get done. One couple walked over to them, the woman was a little taller than Erin and further along in her pregnancy, she had long wavy brown hair and her husband has buzzcut black hair.

"How far along might you be?" The woman asks, holding her husbands hand.

"5 months and 3 weeks, you?" Erin replies politely.

"7 months and 4 weeks, it's wonderful isn't it?" Erin smiles, the woman turned to her husband before facing Erin again.

"I'm Lacy, this is my husband Travis. He just got off a tour in Afghanistan, he's going to be leaving the army and getting a job in the police force or something." Lacy explains proudly, Travis shakes hands with both Erin and Jay.

"I'm Erin, my boyfriend and partner Jay" Erin introduces them. Jay wasn't paying much attention, he couldn't stop tihnking about how right the word 'boyfriend' sounded coming out of Erin's mouth.

"Partner? Are you detectives?" Erin nods, Lacy looks at Travis with a smile.

"When the time comes, could you put in a good word for Travis? He's going to be joining the acedemy, he'll be a good cop" Erin chuckles at Lacy's devotion to her husband.

"Sure, I'd love to help out a marine" Erin smiles, Lacy then pulls out her phone.

"Whats your number? I've been wanting another expecting mother to hang out with while Travis is gone during the day." Erin gives Lacy her number then the instructor calls out that the break is over.

After class, Erin says bye to Lacy then Erin and Jay get in their vehicle. Jay gets a text message from Ruzek, but not work related.

"What does he want?" Erin asks.

"He wants me to go out with them tonight at Molly's, he says you can hang with Burgess at the apartment, says she's got stuff for you" Jay says.

"Sure, but if you can't drive you call me okay?"

"Yes dear" Erin slaps his arm and pulls into the parking lot of their apartment.

"Wait, give me a kiss" Jay grabs Erin's arm and pulls her back into the seat, She kisses his cheek then gets out.

"That's not what I meant" Jay says.

"You said you wanted a kiss, I'm pretty sure that's what I did, did I not?" Jay sighs, knowing he'll never win a sarcasm battle with Erin Lindsay.

"So tomorrow night Voight, Justin and Olive are coming over for dinner. Remember Olive is 9 months pregnant so do not be an ass to Justin or her, got it?" Jay gives Erin an 'are you kidding me look? what did I ever do?' look.

"I'll try, only because if I don't your crazy hormones will put me six feet under" Jay jokes. Erin stops where she stands, outside the door of the apartment.

"How about you try carrying a child for nine months and staying completely level headed! This is harder than you can imagine and I'm sorry if my hormones don't settle well with you!" Erin shrieks.

"I'm sorry, I'm sorry, that's not what I meant. Erin I'd do anything for you, it was just a joke. I'm sorry" Erin takes a few deep breaths and opens up the apartment door.

"Keep saying things like that and you can spend the night on the couch" Erin threatens. Jay raises his hands in defense, Erin chooses to ignore it and heads for the bathroom.

"I'm taking a bubble bath, could you order chinese please?" Erin says before shutting the bathroom door.

"Yeah, you want the usual?" Jay yells back.

"Yeah!" Erin replies, the sound of water and music playing fills the apartment, Jay heads out into the hallway to order chinese.

A/N- How was this? I kinda like this chapter to be honest, and I would love to have Erin and Jay never fighting but that would make the story boring ;) so please leave feedback and enjoy this chapter until the fall finale! There best be some Linstead in there or I'll cry ;(
