(A/N): Oh boy. Why did I write this?

Chapter One: And baby makes three?

It wasn't supposed to happen. A drunken mistake. Marinette sat on the edge of the bathtub, staring down at her 12th pregnancy test. It read positive. Just like the 10 others before it. Only one had read negative. She should have known that sharing an apartment with someone who could potentially get her pregnant was a bad idea. Especially with her pent-up feelings.

She sighed and stood up. Marinette knew that she would have to tell Adrien sooner or later. He had to be the father. She hadn't... with anyone else. 22 and pregnant. She threw the stick in the trash and covered it, along with the rest, with a few squares of toilet paper. After washing her hands, she strolled out of the bathroom and smiled weakly at Adrien, who was sitting with his feet folded under him as he waited for her to start up the movie he wanted to show her.

Marinette sat down next to him and he turned to her grinning excitedly. She managed to keep her weak smile in place. Adrien picked up on her discomfort almost immediately, his eyebrows creasing in worry.

"What's wrong? Do you feel okay? Is it that time of the month, cuz I have a stash of chocolate if it is." He asked, going over a mental list of how to help cramps.

"No, I'm fine, Adrien. It's just been a long day. I'm excited about this movie though." She didn't know how to tell him.

In truth, it was her time. Or rather, last week was. She had thought she was being paranoid when she had made a trip to the drug store on her way home from work but she had never been late. Never. As it turned out, her paranoia had been well placed.

Adrien looked at her in sympathy but gave her a warm smile before turning to face the tv again. He picked up the remote and snuggled close to her before pressing play.

By the end credits, Marinette was half asleep on Adrien and he had to pee something fierce.

"Mari... Maaaaaarrrriii... Marinette..."

"Hmmmmm..." She replied lazily.

"I got to go... could you move a little bit?"

With an exaggerated groan, Marinette rolled onto the carpet. Adrien stood, laughing, and strolled to the bathroom.

Normally, Adrien wouldn't notice the trash can. Normally, he would dry his hands and leave the bathroom. Normally, the trash can would be under the bathroom sink. But instead, the trash can was placed haphazardly to the side of the toilet with toilet paper streaming out of it.

Shrugging to himself, Adrien picked up the garbage to empty.

Marinette did not want to get up and walk aaaaaaaalll the way to her bed. It was just too far. She slowly crawled across the floor in the general direction of her room.

Hearing the bathroom door open and the lights flicker off, she flopped down in the middle of the hall, hoping that if she looked pitiful enough, Adrien would carry her to bed.

Adrien left the bathroom, trash in one hand as he flicked the lights off with the other. Squinting into the dark room, he tried to maneuver around pieces of furniture. Sadly, he wasn't expecting a melodramatic Marinette to be lounging five feet ahead of him. His foot caught her leg and, in an effort to not land on top of her, he lunged forward and toppled over. The trash slipped from his hand and flung down the hall, spilling its contents in the process. Plastic clattered to the floor.

"What in the...?" Adrien said standing up and reaching for the hall light.

Marinette moaned and then let out a halfhearted yell of pain when he flicked on the lights. Pregnancy tests littered the hallway. Adrien walked over to one and crouched near it as Marinette rolled over and pushed herself up into a sitting position. She glanced over to Adrien as he picked up the plastic. Suddenly, Marinette didn't feel so tired anymore.

Launching herself forward, she clumsily slid down the hallway and snatched the test out of his hand. He looked up at her with something close to hurt written on his face.

"Is... is that a pregnancy test?"

Marinette's eyes widened as her brain tried to come up with some way to convince him that she isn't pregnant with his child.

The most eloquent thing her brain came up with was, " They're for a friend!"

"Used and in the trash?" Adrien asked, catching her malformed lie.

Marinette shrugged and looked at the floor. The test fell out of her hand and landed loudly.

Adrien watched her stare at her feet for a few tense moments before retrieving the trash bag and collecting all 12 tests. The easy to read screen read positive on eleven of them. He walked pasted Marinette, threw the garbage into a bin and washed his hands.

Back in the hallway, Marinette decided now would be a great time to go to bed and sleep for the rest of forever. As her hand closed around her doorknob, Adrien reappeared in the hallway.

"Mari... wait?" It was phrased like a question, a plea.

She stopped but didn't move to look at him. He reached her in four long strides.

"Are you pregnant?"

It was a simple question, really, but Marinette knew that the answer was much more complicated than yes or no and frankly she didn't feel up to talking.

"Can we do this in the morning?" She asked softly, begging for the sweet relief of sleep.

Adrien sighed and nodded, watching as Marinette turned her doorknob and shuffled inside. He continued to stand dejectedly in the hallway for five minutes before he went into his own room. Plagg greeted him with a complaint about a lack of cheese in his stomach. Adrien ignored him as he got ready for bed. He crawled into bed ten minutes later, feeling restless. He barely slept.

In Marinette's opinion, morning came too fast. She was woken up by sunlight filtering in through her window. She groaned and turned over, almost crushing Tikki in the process.

Marinette thought she had managed to keep the possible pregnancy from Tikki until last night when she explained the whole situation. Tikki then admitted to being able to sense the slowly developing baby. The possibility became a reality when Tikki confirmed that Marinette was definitely pregnant.

A knock at Marinette's door forced her out of bed. Glancing back to make sure Tikki was well hidden, she pulled the door open to reveal a drained Adrien.

"Breakfast is ready." He mumbled, swaying slightly in place.

Marinette nodded and followed him into the kitchen. Fresh croissants were on a plate in the center of the table and a mug of black coffee was in front of each of the two plates that were set out. Marinette sat in the closest chair and immediately reached for a croissant. She bit into it as Adrien took the seat across from her. He didn't move to take a croissant, instead just watching her eat.

After about ten seconds of intense staring, Marinette put down her foot and crossed her arms over her chest.

"Yes, Adrien. I'm definitely pregnant and it's definitely yours."

Adrien's mouth hung open like a door on a hinge.

"Are you gonna eat something or are you just going to stare at me while I eat?" Marinette asked awkwardly as she picked up her half-eaten croissant.

Adrien's mouth snapped shut and he leaned forward to shakily pick up his breakfast. Marinette finished eating and cleared her plate, leaving the mug of coffee untouched. She left the kitchen to get ready for the day. Thankfully, it was her day off so she had time to wrap her head around sudden motherhood.

After showering and getting dressed in clean clothes, Marinette wandered out of her room. Adrien wasn't in the kitchen or living room. Marinette shrugged to herself, deciding he was probably hiding in his room. She plopped down on the couch, wondering if she should talk to Adrien. Ultimately, she determined that talking would probably make things a little bit less uncomfortable.

She pulled herself up and walked back to his room. She knocked on his door and waited for him to answer. After a minute of waiting she knocked again. Another minute. Another knock. Another minute.

Marinette turned the knob, slowly opened the door, and peeked in. A quick glance around told her that he wasn't in his room. She slipped back out and shut the door. Walking back by her door, she noticed a yellow sticky note pressed flat to it.

'Marinette,

Going out, will be back.

Adrien.'

Marinette's stomach sank like a stone. Did Adrien run away? That didn't sound like him but the note was definitely suspicious. Where did he go? When would he be back? Marinette suddenly felt super queasy. She darted to the bathroom, yanked open the toilet, and threw up everything in her stomach. She stood trembling for a few moments before washing her mouth and hands and shakily walking to the couch.

She laid down and closed her eyes, praying for the room to stop spinning. Taking a deep breath, she started to reason with herself

'Adrien didn't leave. He wouldn't do that to me. He cares about me. Worrying about this is stupid. He wouldn't do that. He wouldn't do that. He wouldn't do that. He wouldn't do...'

The front door slammed open.

"Ouch! Stupid... ugh!" The loud noise of Adrien dragging something heavy through the hall rang through the apartment.

Marinette launched herself off the couch, ignoring her protesting stomach and racing to Adrien. She stopped when a large box blocked her path.

"Marinette? Are you okay? You look a little pale..." Adrien asked, letting the bags he was carry drop gently to the floor so he could reach over and check her temperature with that back of his hand.

"I'm fine," she said, looking down at the multiple bags and large box resting on the floor, "what's all this?"

"Uh... it's baby stuff..." he muttered, looking guilty.

"Baby stuff?"

Marinette looked closer at the bags to find newborn clothes, a few room decorations, diapers, bottles, parenting books, and what appeared to be a breast pump. The large box had to be a crib.

"Adrien. I'm only a few weeks pregnant. This is overdoing it a bit."

"I know," he replied, ducking his head, "I just want to be prepared."

Marinette giggled, her stomach pains and worry completely forgotten. Maybe motherhood wouldn't be so difficult after all.
