Amy flopped onto the couch after putting in the movie for the kids. She just needed them entertained for a few minutes before she got started on dinner. She had started working with another research professor as well as teaching this week, and the tiredness was slowly creeping up on her. She thought she could use this weekend to relax with Sheldon, but he and Leonard had left since Thursday to speak at Princeton about their new paper. She took off her glasses and rubbed the side of her head to try to ease the headache that was starting again. She didn't even have the energy to cook. "You guys want pizza?" she asked the two-year olds, and was met with toothy grins.

The delivery guy gave her a 20-minute estimate, 'just enough time to take a power nap' she thought as she set an alarm on her phone. She woke up sometime later not to her alarm but to the doorbell. She glanced at Stephen and Marie still watching the movie. She got up to get the door and the room started to spin, she reached out to grab the couch to stabilize herself, 'must have got up too fast' she thought as she answered the door. She paid and tipped the guy and went back to the couch with the box. She didn't even bother getting plates.

Some time later she noticed Stephen rubbing his eyes, "Tired baby?" she asked as she ran a hand through his hair. He only snuggled into her side as a response. "Time for bed" she announced taking off the tv, she stood up from the couch causing Stephen to whimper and stretch his hands up. She lifted him up and placed him on her hip only to hear Marie whimper, she turned to see her looking with big green pleading eyes, "Fine" she sighed, picking Marie up from the couch.

"Daddy story?" Marie asked when Amy finally got them to bed. Sheldon formed a habit of reading the little engine that could every night before they went to bed, and Amy knew there was no way they were going to sleep without it. He had face-timed the other night, so she was sure he would do it again. "Sure baby, let me get my phone" she said reaching around, only to realize it was nowhere in sight. 'Where's my phone? I had it with me?' she bowed her head when she remembered that she left it downstairs on the couch. 'I guess the tablet could work' she thought going to her bedroom to get it.

She couldn't help but doze off a little as Sheldon read the story. She woke up when she heard her name being called repeatedly, she looked around to realize the twins were asleep with the tablet between the both of them. She carried Stephen to his bed on the other side of the room and tucked them both in. She turned off the light and picked up her tablet to see her husband's face

"You look a little worse for wear" he teased

"Gee, thanks" she said sarcastically

"I take it today was another long day?" he asked

"Yeah, it kinda was" she said lying down in bed.

"You're not going to change first?" Sheldon asked

"Yeah I would, just wanted to rest a little. Tell me about your day."

Sheldon went into vivid detail about his day. He looked away for one minute to talk to Leonard and when he faced the screen again, she was fast asleep. He tried calling her name, but she wouldn't budge. He chuckled to himself and took a screenshot of her sleeping face, then hung up his phone.

Amy woke up the next morning in the center of the bed. She heard someone walk in and turned to see Sheldon.

"What are you doing here? I thought you were coming back tomorrow?" she asked

" The talk for today got cancelled, so we decided to come home." He said coming to join her on the bed

"What time did you even get in?"

"A little after 4. You fell asleep in your clothes."

She looked down to realize she was only in her underwear, "Oh"

"You left the lights on downstairs" he said

"Oh geez. I was supposed to go down and turn them off when I went for my phone. I forgot"

"Its okay" he said kissing her cheek, "I was just about to make breakfast. You coming?"

"Yeah. I feel hungry" she said standing up from bed. As soon as she was upright the room started spinning causing her to sway a little on spot. Sheldon reached out a hand to steady her, "You okay?" he asked

"Yeah, I just probably stood up too fast" she said moving to get her robe.

This was all giving Sheldon a déjà vu feeling. The last time she was like that was when she was pregnant with the wins. She can't be. Marie and Stephen were supposed to be the first and last ones. "Amy are you sure you're not sick?"

"I feel fine. It was just a long week"

'Maybe she was right. Maybe she was just overworked and tired.'

"What do you want for breakfast?" Sheldon asked the twins

"Eggs" Stephen said. The kids never followed his eating schedule. He could get Stephen sometimes but most times he didn't fight it. Amy walked near Sheldon as he cracked the eggs and felt her stomach churn.

"Are you ok?" Sheldon asked seeing her facial expression

She took some deep breaths trying to calm her stomach, "Do those eggs seem okay to you?"

"They seem fine to me to me" he said lifting the bowl to his nose. He pushed the bowl towards her face and she couldn't hold back any longer. She clamped a hand over her mouth as she retched and ran towards the bathroom.

"Momma?" Stephen questioned as they heard Amy violently throwing up. "Don' t move okay?' Sheldon said, before going to the bathroom. He entered the bathroom to see Amy dry heaving. He helped her lean against the wall and closed and flushed the toilet.

He sat on the floor opposite from her, "I don't thinki there was anything wrong with the eggs" he said

"I know" she sighed, not bothering to open her eyes.

"But it made you sick?"

"Mhm" She opened her eyes to look at him, "I know. I'll take a test, although we don't really need anymore conformation."

He looked up to meet her tired eyes, "How did you know I was thinking that."

"I'm late. A part of me thought it was this but I dunno. It just didn't seem concrete enough until now"

He reached forward to push the hair from out of her face and cupped her cheek. "I thought Marie and Stephen were supposed to be the only ones" she whispered

"Well, then this baby would be our last"
