Being Atsumu’s Pregnant Partner:
YN goes into Labor

Atsumu Miya x Pregnant! GN reader
Warnings: swearing, pregnancy and a lot of stuff to do with pregnancy, mentions of throwing up and bodily fluids
***pregnancy is different for everyone and I’m basing this off my own personal experience
AN: *sigh* friends I’m having major baby fever and since I’m forever done diy-ing my own, I shall instead write about it 😌 maybe I should just get a kitten
Looking back now, it probably wasn’t the best idea to go to a professional, five set volleyball match at 39 weeks pregnant but here you were. You’d always been the devoted type, doing anything and everything you could to support your man no matter what.
Atsumu Miya wasn’t always the easiest partner to have but you loved the big dummy. He was extremely dedicated to his sport and team, which made dealing with him outside the court rather bothersome at times.
Nevertheless, you decided that you could stand just enough of him to spend your life by his side and raise a family. His brother, Osamu, asked you about a million times is you were for sure ready to raise a baby Miya. He knew exactly what it would be like because he was one.
At first you laughed it off, thinking that you had a few years of rest before the chaos would ensure but man, were you wrong. You’d become pregnant relatively quickly, making both you and Atsumu extremely excited.
However, your excitement soon dampened as you began spending most of your day hugging the porcelain thrown or downing antacids to help with the wicked indigestion that crept up your throat at every turn. Your breasts ached, your sleep suffered and the smell of nearly anything sent you running to the bathroom. Your skin broke out, hair began to shed, and most days, you felt like a Sméagol from lord of the rings, just trying to protect your unborn baby.
Atsumu had been as supportive as you imagined he’d be. This mostly meant calling Osamu to make you something to eat or google home remedies to help with your morning sickness. Osamu was also extremely excited for his little niece or nephew to make their appearance, doing whatever he could when Atsumu was gone to help you.
You’d managed to make it all the way to 39 weeks, and you were excited to finally be done. The doctor had scheduled an induction for the following week because of blood pressure issues. You weren’t exactly stoked about the idea of an induction but the fact that you’d be able to meet your baby soon was thrilling.
You waddled your way through the crowd, waving to people as you passed. Akaashi had stopped to talk with you as well as Asahi and Suga. It was nice to see everyone again even though you were exhausted.
“There they are!” Osamu yelled, waving you over to his Onigiri stand as you huffed and puffed, finally able to stop. The pressure from the baby was making it difficult to walk, your pelvis hurting as you leaned on the corner of his stand, his chuckle causing you to glare at him.
“You know you could have stayed him YN. Sumu pays for the expensive sports channels because he’s obsessed with watching replays of his games, I’m sure you’d see him on there,” Osamu joked as you motioned for a delicious looking Onigiri in the corner of the display case.
“This will probably be the last game Sumu plays in for a bit because of his paternity leave. I don’t want to miss it!”
Osamu chuckled, shaking his head as you made your way to the stairs of the bleachers. Your phone rang as you began to ascend, huffing and puffing as you walked up.
“Hello,” you answered as the noise of the locker room filled your ears.
“Hey baby! Did ya make it?” Atsumu shouted back as you finally found your spot and took a seat releasing a heavy sigh as you settled in.
“Not up as high as I normally go but my feet hurt too much to even care.”
Sumu laughed as you looked around to see the stands filled with people.
“Well just relax baby, this time next week will be in the hospital having our baby!”
You groaned just thinking about the idea of pushing out this child, knowing that the possibility of having a small baby was out of the picture.
“Yeah yeah, just make sure you win today, ok? I don’t want yo moping around the house for the next week!”
Atsumu laughed loudly as you smiled. He agreed and hung up the phone, knowing you’d be there to support him no matter what happened.
The teams took their places, and the match began without a hitch. You knew it’d be a long one by the sheer energy happening around you. Two sets had already taken place and the teams were tied. You watched as Sumu slammed a service ace right into the opposing team's court. Your man was on fire today, probably excited about everything happening around him.
The pressure of the baby on your bladder, pushed as you tried to adjust, not wanting to walk out right in the middle of Sumu’s serves. Of course, you knew his serves could go on for a while, so you finally caved, as you thought about the nearest bathroom.
Standing up, you felt a twinge hit. Your back began to radiate pain as it moved to the front of your belly. You gritted your teeth, gripping the side of the chair as you grabbed your stomach.
“Are you ok?” Someone asked as you turned to them confused and nodded. There was no way this was anything more than Braxton hick's contractions, right?
The pain subsided as you assured the person you were ok and made your way to the bathroom. In the bathroom, you noticed you had started losing the mucus plug your doctor had talked about. You knew this meant nothing and weren’t concerned as you continued to feel the baby kick in your stomach.
Washing your hands, you felt the pain against radiate from your back to your front. You had no idea how far apart these pains were as you quickly grabbed your phone and waited for the pain to subside.
Hitting the timer, you exited the bathroom and made your way back to your seat. You felt another pain hit as you quickly checked the timer.
7 minutes.
Standing on the side, you waited for the pain to pass again before ascending the stairs. At this point, you were clearly in denial that anything was happening. Surely these were only practice contractions. Your body had done them before but then again, they’d never felt quite like this.
You restarted the time as you finally sat down, trying to remain calm as you focused back on the game. A few minutes passed again before the pain started, only this time, you felt a pop, followed by a trickle of water fill your pants. You began to stand up as the pain emanated through your stomach.
“Hey Yn- YN HOLY CRAP!” You heard someone yell as Osamu came running over you to, abandoning the Onigiri in his hands to grab onto your arm and steady you.
“Samu the baby, I think the babies coming!” You whined as Osamu’s eyes widened at you, the crowd cheering as MSBY scored yet another point.
At this point, you had tears in your eyes, the pressure from the baby pushing more fluid from your body as the pain continued to radiate. You leaned hard on Samu, groaning as you tried to make it through the pain.
Osamu looked around for anyone he knew, anyone who could possibly help him get you downstairs and to the hospital. As if on cue, he looked down to see Sakusa’s eyes locked with his. He knew his best bet at this point was to try and signal to Sumu that you were in labor.
“YN’s in labor!” He mouthed as Sakusa’s eyes widened and he turned to Sumu who was in the back row. Sakusa wasn’t sure what to do as Sumu was preparing to serve yet again. He wasn’t a person to normally shout but then again, it wasn’t everyday his teammates partner was in active labor at a game.
He looked over to the coach who was now concerned about what was going on with him and why he continued to trail his eyes into the crowd. At this point, Hinata had begun to notice as well, his eyes following Sakusa’s as he saw you, bent over and holding your stomach as Osamu supported you.
“Holy crap YN’s in labor!” He shouted just as Sumu threw the ball up the serve. His eyes widened as his palm made contact with the ball.
“WHAT!?!” He bellowed, sending the ball slamming hard into the other side of the court as the whistle blew signaling the end of the set.
Atsumu quickly looked up to see Osamu helping you down the stairs as you breathed, your face contorted in pain.
“Shit Yn!” He shouted, quickly taking off into the crowd to get to you. He ran as fast as he could, dodging people left and right until he finally met you at the base of the stands.
“YN’s definitely in labor Sumu, their water broke and everything. Contractions are 7 minutes apart right now, but they are in a ton of pain,” Osamu recited as you moaned through another painful contraction, Atsumu grabbing onto your belly and helping lift it to relieve some pressure.
He hadn’t been super eager to take the birthing class suggested by your doctor, but he had to admit, the techniques were coming in handy.
“Sumu the game!” You whined as the contraction ended. Sumu shook his head vigorously before he was interrupted.
“Don’t worry about the game Yn, we will put in our sub and thanks to Sumu’s service ace, we are ahead a set,” Coach answered, coming up with Meian and Sakusa
“Just worry about having that baby Yn!” Meian chuckled as you smiled.
“Please take YN to the hospital now, do you know how unsanitary birthing a baby here would be?” Sakusa demanded as Atsumu blindly nodded and took control of you, Osamu running ahead to grab his car to help.
At the hospital, the doctor checked you before the anesthesiologist made their way to you, providing you with a moment to breathe. Osamu was waiting outside, not wanting to miss the birth of his brothers baby.
“Don’t you wanna watch the game Sumu?” You asked as your partner came beside you and grabbed your hand.
“Nah, Hinata texted me and told me we won. I’ll just watch it when we get home from the hospital. Plus, I want our baby to see how awesome I look on TV!”
You giggled, laying your head back as you rested your body. Atsumu right by your side as you entered this new stage of life together.
