Requested by ShawnieP00 . Enjoy! Y/N is 16 yr old lil sis.
——————————————————
You had just finished a hunt and were pretty sore, but not so sore that you didn't notice something was up with your body. You noticed a faint pain in your right side, not too bad, but it was there, but you had been slammed into a few walls, so you were probably bruised to high heaven.

You paced around the the motel room, waiting until it was your turn for the shower, since all three of you had been covered in grime by a ghost.

"Y/N? You okay? You're awfully agitated..." Sam observed, noticing the pacing you were doing.

"I'm fine, Sam, just antsy after the hunt. It happens sometimes." You say nonchalantly, as you absent-mindedly start rubbing your right side.

"Is your side okay? You took a lot of hits to it?" Sam asked, stepping into overprotective big brother mode, as a sign of pain flashed in your eyes.

"I'm fine, just bruised." You say with a laugh, that hurt like a sonuva, so much so you paled and almost doubled over.

Dean emerged from the bathroom looking refreshed and clean as a whistle, stopping when he saw you were pale.

"What did I miss? Are you okay?" he asked, automatically in brother mode too.

"Ohmygosh! Shut up! I'm fine." You yell angrily, walking into the bathroom and slamming the door shut for emphasis. You stand there for a moment, furious, too pissed to realize how hard you were breathing was increasing your pain exponentially. You doubled over, gasping loudly, as pain shot through your right side and pelvis.

Once the pain eased slightly, you took a quick shower, ending up taking a long time because the pain was getting steadily worse and stayed at a consistent throb.

You hobble out of the bathroom, once you got dressed, having struggled with it all as each breath sort of hurt.

Neither Sam nor Dean looked at you, telling you that you'd struck a nerve earlier.

"Um... I'm sorry for yelling at you for worrying about me." you say finally, as you walk over to Dean and offer him the hair brush. "Can you braid my hair? My side hurts too much" you admit.

Dean beamed at you, immediately setting to work on your hair, as soon as you sit in a chair in front of him.

Sam walked over and checked your side, seeing no bruising, before looking up at you curiously

"When was your last period, Y/N?" he asked gently, earning a pointed look from Dean.

You blush deep red, as you wrack your brain. "I just had it." You say, knowing the pain had nothing to do with your period.

"You aren't bruised, even a little bit." Sam said calmly, pointing at your only slightly swollen side. "Slightly swollen though." he said.

"It hurts only on the right side, from my ribs to my pelvis." you explain, starting to feel frustrated again. You could tell neither of your brothers had any clue what was going on, or how to help you, and the idea left you feeling kinda queasy.

Sam sighed softly, seeing your frustration, and stood up, backing up quickly. " I know that's what you feel, but I don't see any cause, maybe you're going to have a weird period." He suggested, turning and walking away.

You clench your teeth in irritation, throwing your hands up in the air with a "Gah," of annoyance. Which only left you in tears from the pain that was only getting worse, and making you more and more nauseous.

"Y/N, you're really out of sorts. What's wrong?" Dean asked, having stayed silent the whole time to be the neutral party both Sam and you could run to.

You sniffle softly, turning around, as he finishes your last braid, and try to lay your head on his shoulder but yelp and shoot upright, because it hurts too much.

"I don't feel good, Dean. My stomach hurts, and it's making my queasy." You admit softly, putting a hand on your now slightly swollen lower stomach on your right side, only to grit your teeth and pull your hand away.

"Why don't you go lay down for a bit?" Dean suggested, confused by how you said you didn't feel good. It didn't sound normal, which had him really worried for you.

You hobbled over to the bed, feeling more and more queasy as each step was more excruciating than the last. You collapsed on one of the beds, whimpering softly, as the pain nearly exploded in your side from the movement.

"Y/N?" Sam asked, hearing you whimpering. He couldn't help worrying about you, as he walked over to check on you. He touched your forehead lightly, his hand much cooler than your flushed skin. "She has a fever, Dean." he said.

Dean walked over, testing for himself, before walking over and grabbing the thermometer and checking your temperature. "102.4." he said, when it beeped.

"That's a pretty good fever, Y/N, no wonder you don't feel well. Definitely not your period..." Sam said thoughtfully, wondering what could possibly be wrong with you, when you suddenly lurched forward, vomiting pure blood on the ground. He stood frozen, too stunned to react right away, or be able to think about how to react right away, as he watched you vomit pure blood again.

Dean sprang into action, grabbing a garbage can, catching the second round, and grabbing a towel to clean up the first round.

When you got a break, you noticed that the pain had stopped in your side, and looked at Dean in concern. "The pain is gone." you said hoarsely, before doubling over and vomiting up more blood.

Sam seemed to wake up hearing you say that, and snapped into action, scooping you up and carried you out to the car with your trash can. "We need to go to the ER." he told Dean, who nodded and got in the driver's seat.

The drive, arrival, and check-in were a blur of bloody vomit and curse words, leaving Sam and Dean in the waiting room awaiting news of if you were going to be okay or not.

"Family for Y/N Winchester!" Dr. Wilson called.

Sam and Dean sprang to there feet and walked over, and were escorted to your room before anything was explained.

"Y/N is very lucky to be alive, her appendix ruptured. We had to remove it and repair the damage, she has to stay for observation for a week and antibiotics for a month. But she should be just fine." Dr. Wilson said warmly.

Sam and Dean sat at your side until you woke up, and kept you company all week, before springing you from the joint. They kept a close watch over you for a the following month, and demanded you take all your disgusting antibiotics.
