A/N: Fem!Bucky AU.

For a while now, Bucky had been feeling off. She had been having on again/off again nausea for about a month...and now her period was late.

"Ah, sh*t, f**k!" Bucky exclaimed when she realized what could possibly be wrong with her.

But before she can tell Sam anything, she wants to be absolutely sure that her suspicion is correct. So, she sets up an appointment with her doctor. On her way out of the Avengers compound, Bucky runs into her boyfriend, Sam.

"Hey, babe, where you running off to?" Sam asked her.

"Just going to a doctors appointment." Bucky replied.

"Want me to come with you?" Sam asked, gently cupping Bucky's cheek.

"No, it's okay." Bucky assured him.

"Well, alright, see you later. Love you." Sam said, kissing Bucky's forehead.

"Love you too." Bucky said, kissing Sam's cheek.

Bucky heads to her doctors appointment where they run a few tests.

"The results just came back, and it seems that you are indeed pregnant, Miss Barnes." the doctor told her.

"Are you serious!? Me!? Pregnant!?" Bucky said, shocked.

"This doesn't make any sense, Sam and I always use condoms." she added.

"Condoms don't always work, they're only 97% effective." the doctor explained.

"Really?....they should put that on the box." Bucky replied.

"They do, ma'am." the doctor chuckled.

"...w-well...they should put it in big bold letters. Make it easier to see." Bucky grumbled.

"Here's some pamphlets about prenatal care. Do you have anymore questions?" the doctor said, handing Bucky the pamphlets.

"No, I'll just go home now." Bucky sighed, stuffing the pamphlets into her purse.

When Bucky got back to the compound, she goes to her and Sam's room and flops face first onto the bed. She was worried about how Sam would react to her being pregnant. Would he be happy? Would he be upset? Would he deny that the child is his and leave her? The uncertainty overwhelmed her to the point of tears...though most of the crying was because of hormones.

"Bucky, are you okay? Why are you crying?" Steve asked knocking on the door.

"Go away, Steve, I'm fine." Bucky cried, her voice muffled by the mattress.

"You don't look fine to me." Steve said coming into the room.

As he sits on the edge of the bed, he accidentally knocks Bucky's purse off, causing it to fall on the floor and spilling a little.

"Oops, sorry." Steve said, picking up the purse and putting the stuff that spilled out back in.

But then he noticed that one of the things he was holding was a pamphlet on prenatal care.

"Bucky...are you pregnant?" Steve gasped.

"...yeah..." Bucky mumbled rolling onto her side.

"Have you told Sam yet?" Steve asked.

"No. I just found out myself." Bucky answered, sitting up.

"Do you think Sam would even want to have a baby with me?" she asked wrapping her arms around herself.

"Oh wow, pregnancy brain really is a thing, cause that was the stupidest thing you just said." Steve said grinning.

"EXCUSE ME!?" Bucky snarled.

"OW!" Steve laughed when Bucky punched him in the ribs.

"Buck, what I meant was that Sam loves you and would never leave you for any reason." he said, rubbing the area he was punched.

"You really think so?" Bucky asked, leaning her head on Steve's shoulder.

"I know so. I'm certain that Sam will be a great father." Steve said, wrapping an arm around his best friend.

"There you guys are, suit up there's an alien invasion going on in Miami." Scott said poking his head into the room.

With that being said, everyone suits up and grabs their weapons...well, except for Bucky.

"Why aren't you ready, babe?" Sam asked.

"I, umm, I'm not going. I'm not feeling well." Bucky replied shyly.

In all honesty, she was feeling a bit nauseas at the moment. Why the h*ll do they call it 'morning sickness' if it happens all d*mn day!?

"You look fine to me." Tony said skeptically, raising an eyebrow.

"Are you seriously suggesting that I'm faking being sick right now!? What me to throw up on you as proof!?" Bucky growled, gritting her teeth.

"Okay, okay, I believe you!" Tony replied, shielding himself with his arms.

"You gonna be okay? Do you want me to stay with you?" Sam asked, worriedly.

"Don't worry about me, you guys just go and kick alien a**." Bucky told them.

Before leaving with the other Avengers, Sam kisses his girlfriend and tells her to call if she needs anything. Then he tells Peter to stay behind to keep an eye on her. Once everyone was gone, Bucky rushes to the nearest bathroom to throw up in.

"Miss Barnes, are you okay? Anything I can do to help?" Peter asked, knocking on the bathroom door.

"Can you come in here and hold my hair back." Bucky grunted.

"Umm, sure." Peter replied softly.

So, Peter kneels behind Bucky and holds back her hair as she pukes up her guts into the toilet. When there was nothing left in her stomach, Bucky leans back into Peter's chest.

"FRIDAY, what's wrong with her?" Peter asked the A.I..

"Miss Barnes is pregnant with Mr. Wilson's child." FRIDAY replied.

"Oh cool, congratulations." Peter said picking Bucky up off the floor.

He carries her to the common area and places her on the couch.

"I'm gonna get you some water, you lost a lot of fluids." Peter said covering Bucky with a blanket.

"Okay...and get me some food as well, I'm starving." Bucky said.

"Ummm, are ya sure that's a good idea, I mean...you just got done throwing up." Peter replied, nervously rubbing the back of his neck.

"But....I'm hungry." Bucky said with a puppy-dog pout.

"How about we just stick to water for now, keep ya from getting dehydrated." Peter suggested with a nervous grin.

"Fine." Bucky grumbled harshly.

As Peter gets the pregnant woman a glass of water, Bucky watches some TV. And then suddenly she had a bone deep feeling that something terrible was going to happen. Now she's anxiously hoping that Sam is okay.
