So, I have been fighting with myself over this story. I really didn't want to write this because I wouldn't be able to add all the science stuff to an extreme level. Like almost all of Sheldon's dialogue is. I've never been great at science and I just pick up the stuff from BBT. So, please bear with me on this story.

This starts after the Halloween episode.

Penny sat on the couch reading her history text book. She knew she had Amy and Bernadette to help her if she couldn't write a good paper, but she really wanted to write the next one on her own as much as possible.

There was a knock on her door so she bookmarked her page and set it down on the table. She stood up knowing already it wasn't Sheldon who was at the door. She pulled the door open to see Amy and Bernadette on the other side.

"Hey," Penny greeted.

"How's reading going?" Bernadette asked.

"It's going." Penny replied. "I'll probably have to do more reading before next week. There's no way I am going to make it to class today." Penny said sitting back down on the couch.

"What's wrong bestie?" Amy asked.

"I just haven't been feeling well all day. I honestly wouldn't stand to close to me, unless you want to get sick too."

At that the two both backed up.

"Do you need anything, soup or something to make you feel better?" Bernadette asked.

"No, I'll be fine. It's really not that bad. I'm just gonna stay home and read up on some history." Penny said picking the book back up.

"Call us if you need anything." Bernadette said as she put her hand on the doorknob.

"We don't care if Leonard is across the hall and capable of taking care of you." Amy added as Bernadette opened the door.

"I will. I promise." Penny said as they left.

As the weeks went by Penny had begun to feel better and could actually make it through work with no issues. It wasn't until it was a few days from Christmas that she started to feel sick again.

Leonard rolled over in Penny's bed to feel the spot next to him empty. He sat up and rubbed his eyes trying to see without his glasses. "Penny?" He called out.

"I'll be right out." Penny said from the bathroom.

Leonard picked his glasses up and put them on. "You ok?" He heard the toilet flushing and the water start to run from the faucet.

A few seconds later Penny opened the door and walked over to the bed. "I'm fine, just had to go to the bathroom." Penny lied.

"Alright," Leonard said before putting his glasses back on the nightstand and lying back down next to Penny.

Leonard drifted back to sleep almost immediately, but Penny lay awake doing calculations in her head.

By seven in the morning Penny still had not fallen back to sleep and had done the same calculations in her head about a thousand times. Each time she got the same result. One that she wished was wrong and right at the same time.

Leonard had started to stir so Penny closed her eyes and pretended to sleep so she could avoid Leonard for a little while longer. She didn't move until well after he had left for work.

She opened her eyes again and stared up at the ceiling. "What the hell have you gotten yourself into Penny?" She questioned herself.

Penny had done a great job avoiding her friends and especially Leonard throughout the holidays. She had not wanted to accidentally say something before she was a hundred percent positive herself. This was not until after the New Year began since her doctor could not see her prior to then.

Meanwhile, across the hall Sheldon had just begun to question Leonard again about what he did to make Penny appear to have disappeared off the face of the earth.

All the while Leonard sat there not listening to him at all, but questioning himself the same question repeatedly throughout the day.

Penny waited until it was after Sheldon left to go do his laundry before crossing the hallway and freely letting herself into 4A.

"Penny." Leonard said shocked.

"Leonard, can we talk?" She asked getting his full attention.

He rotated his chair to face her. "What's up? Where have you been?"

"Um… a lot." Penny said sitting on the couch and not caring she was in Sheldon's spot.

Leonard walked over and sat next to her on the couch. He rotated her body so she was facing him. "Talk to me."

Penny put her legs over Leonard's and looked up at him. "I…um…am…pregnant."

Leonard's eyes widen. "Really?" He asked very surprised.

"Yeah, 10 weeks."

"Is that why you were avoiding everybody?" Leonard questioned.

"I didn't want to say anything until I was a hundred percent sure and my doctor couldn't see me until after the New Year. I was just scared. I'm still scared." Penny told him.

"How long have you thought you were pregnant?" Leonard wondered.

"Remember that day before Christmas when you woke up and I was in the bathroom?" Penny received a nod from Leonard so she continued. "I spent the whole rest of the night calculating the last time I got my period. I was too scared to tell you so I was pretending to sleep when you left for work that day."

"You didn't have to be scared." Leonard said pulling her into a hug. "We're going to be fine."

"Are you sure?"

"Absolutely," He said as he rubbed her back.

What'd you think?
