A/N: Wow! Thank you so much for the reviews! I'm glad you're all happy/excited! And another thank you to inwhatuniverse for the early birthday wishes! :)

Leonard returned that afternoon, after spending all day with Penny and Wyatt, and found Sheldon and Amy huddled on the couch.

"Leonard you're back!" Sheldon said, rapidly whisking his hand away from Amy's stomach.

They had decided not to jinx it by telling anyone yet until they were in 'the safety zone'.

"Apparently." Leonard frowned. "How are you feeling, Amy?"

"Much better." She smiled. "How was your day with Penny and her dad?"

"Brilliant!" Leonard grinned. "So what made you sick? Are you ill? I'm surprised Sheldon is near you if you're sick." He joked.

"Oh, it was something I ate." Amy answered. "I was totally fine afterwards. Just one of those things."

"Yes, just one of those things." Sheldon added, trying to be casual and 'cool'.

Of course he failed.

"Um…Okay." Leonard replied.

"She ate Thai with me last night while you were eating with Penny, and the spice was too much for her." Sheldon added.

Amy cleared her throat loudly, signalling for Sheldon to shut up.

Of course, he didn't…

"So you really don't need to be suspicious about her vomiting in the morning instead of last night. Like Amy said it's just one of those things!"

"We'll see you later." Amy smiled, dragging Sheldon to the bedroom with her.

"Have fun, kids!" Leonard grinned impishly, as he poured some coffee.

Just as he heard the door close, he frowned. "Hang on…Saturday isn't Thai food night!"

..

"Way to go, Dr Blabbermouth!" Amy hissed. "You almost gave it away."

"Well the fact is I didn't actually tell him!" Sheldon replied, crossing his arms. "You know I hate secret-keeping, and if I'm 'Dr Blabbermouth', that makes you Mrs 'Dr Blabbermouth'. You're certainly a lot more blabby than I am!"

Amy rolled her eyes, but it was betrayed by a small smile.

"What?" Sheldon asked.

"Do you realise how much you're turning me on?" Amy purred.

Sheldon stared at her. "How can…? Amy what do you mean? I didn't do anything!"

"You don't have to."

"Okay, that will be your hormones going into overdrive!"

He was about to walk out of the room, but Amy grabbed him by the hand and pinned him to the door, kissing him intensely on the lips, running her mouth down his jawline, neck and eventually his ear.

"Amy, stop. This is highly inappropriate!"

"Why?"

"You're pregnant, and if we engage in coitus we might…Do some damage."

"Sheldon, we've been having sex for the past three weeks I've been pregnant, and we only found out today." Amy replied as she backed him up to the bed and he fell onto it.

"Regardless. We know now and don't want to jinx it." Sheldon answered.

But Amy had already removed her clothes and straddled him, rubbing her bare chest against his shirt-covered torso.

She pulled him towards her with his own shirt collar. "I want you to take me, Sheldon." She whispered in a sultry voice; "So take me, my Texan Stud!"

Her pet name for him drove him crazy, but he still tried to resist.

That was until Amy ran her hand down his body, cupping and rubbing him through his slacks.

In an instant, he had grabbed her and flipped her so that she was on her back, legs apart and he had slipped between them after removing his clothes.

Their lovemaking lasted only fifteen minutes, after which, the couple had laid back down to cuddle.

Amy's head was on Sheldon's chest and her eyes were closed as she regulated her breathing.

"Do you still feel pregnant?" Sheldon asked.

Amy chuckled. "Yes."

"Good."

"You know what's weird? I really do feel pregnant this time." Amy smiled. "Last time I had no idea; no symptoms, nothing."

"Then maybe this is a good sign." Sheldon replied, lacing his fingers through Amy's fruit-scented hair.

..

On Monday, Amy had called the doctor and had been referred to visit a Gynaecologist that Thursday for a dating scan.

As Thursday rolled around, Amy sat nervously in the waiting room, waiting for Sheldon to finish work and meet her there.

He arrived three minutes early, and sat down beside Amy.

"Sorry I'm late." He whispered. "Alex was asking me all these questions. I couldn't leave."

"You're three minutes early." Amy replied.

"Yes, and usually I am five minutes early." Sheldon answered.

Amy raised her eyebrows and read her magazine.

Seconds later, she felt a hand requesting permission to hold hers.

She looked up and allowed Sheldon to curl his hand around hers, in a silent gesture of support.

Amy smiled, and then heard her name being called out.

"Would you like me to stay here or come with you?" Sheldon asked as Amy stood.

"Can you come with me?" She asked. "I'm terrified."

Sheldon nodded bravely and rose to his feet, accompanying his wife into the small room.

"Hi there, I'm Dr Farrow." The brunette haired woman smiled, extending her hand.

Amy shook her hand, and Sheldon reluctantly followed, before taking a seat beside Amy.

"So, this is your first child?" Dr Farrow asked.

"Um…Yes. We were expecting twins just under three months ago, but…Well, I miscarried." Amy answered.

"So the notes tell me," Dr Farrow replied sadly. "I'm so sorry. Although twins sharing a placenta is often risky."

"We didn't know Amy was expecting." Sheldon explained, "She was apparently four weeks pregnant but lost the babies at the same time. She didn't show symptoms like she is this time."

Dr Farrow nodded. "Okay, well that's a positive start; do you have any idea how far along you are now, Amy?"

"The test said 3 weeks." Amy replied.

"Ah, those things aren't always accurate. Just approximate; would you like to hop up onto the bed and we'll perform an ultrasound." Dr Farrow said, patting the examination bed and switching on the monitor and setting up the equipment.

Amy shyly hoisted herself onto the bed.

"I need to ask a few questions first," Dr Farrow said, as she squirted gel onto Amy's stomach. "Have you had any bleeding or spotting?"

"No," Amy replied.

"Have you experienced any pain or discomfort?"

"Discomfort yes, but nothing bad. Just what I would assume is normal for a pregnancy."

Dr Farrow nodded in response as she rolled the wand over Amy's abdomen.

The doctor blinked. "Interesting!"

"Oh God, what?" Amy panicked.

"Amy, do twins run in your family?"

"They run frequently in Sheldon's family. There have been a few cases in mine, but not as many as his."

"In whose side of your family, Amy?" The doctor asked.

"My Mom's." Amy replied. "I wasn't a twin and neither was she, but my grandmother and great aunt were. They were fraternal I believe."

"You never told me that." Sheldon said.

"Because I thought that was the only case of twins in my family." Amy replied, "But apparently I was wrong. Every third generation in my family. Plus I only just found out recently after I spoke to my mother about the twins."

"Fair enough." Sheldon nodded. "Why do you ask, Dr Farrow? Our twins never made it."

"Hmm no, but these ones did…" The doctor responded, pointing to the screen.

In amongst the grey fuzzy image of Amy's uterus, there were two small round masses spaced a little way apart.

"These are actually measuring 5 weeks, and are growing at a healthy rate." The doctor grinned. "Congratulations!"

Sheldon's face fell. "Wait…Five weeks?" He looked at Amy. "We were still in Florida then, and that was when we were using protection because we agreed to try again when we came home."

Amy frowned at him. "That sounds a little accusatory!"

"Well, how can this have happened? Believe me, I'm thrilled, but…I can't help but wonder…"

"If I was unfaithful to you!" Amy snapped. "How dare you even insinuate that I'd do such a thing? I'm around you all day, every day, unless I am at work!"

"Sir, it is possible that the condom could have torn." Dr Farrow stepped in calmly. "Whether the tear was visible to the naked eye or not, is irrelevant. A sperm cell is only…"

"55 microns in length. I know." Sheldon sighed. "Unless we ever did it unprotected around that time?"

"We had shower sex a few times." Amy muttered.

"Ohhh! You're right." Sheldon said in reply, "I thought that because we were in water…"

He didn't get to finish his sentence before Dr Farrow shook her head. "Nope. That's only really applicable to baths and swimming pools…And also hot tubs."

"Oh. How could I have not known that?"

Dr Farrow shrugged. "Anyway, because of previous complications, your midwife and I will need to see you more often to make sure everything is okay. I can contact our finest midwife, who is actually available now as her last client just gave birth. I'll give her a call and let her know." Dr Farrow said, as she left the room. "I'll be back with you in a minute."

Amy and Sheldon sat in silence for a few moments.

"I can't believe you almost accused me of cheating on you!" Amy hissed.

"I am so sorry. I just thought…"

"I know what you thought. Jackass!"

Sheldon looked sad for a moment. "I'm sorry; that was wrong of me. I know you would never be unfaithful. I was just shocked, I guess. You know, they really should put warnings on condom packets."

Amy frowned at him. "They do. They say 'not 100% effective; for peace of mind, use in correlation with other methods of birth control."

"Oh." Sheldon shifted uncomfortably. "I did not read that part."

Amy giggled. "It doesn't matter. This is a good thing…Well, maybe. We're already a week ahead of where we were before."

"That's true." Sheldon nodded.

He realized that Dr Farrow had left the monitor on, and he stood up and sneakily picked up the wand, running it over Amy's stomach again, until he saw the two little masses on the screen again.

"Sheldon, what are you doing? You'll get in trouble!" Amy giggled, looking round at the screen.

"They look so strange!" Sheldon commented.

"They won't stay like that forever." Amy replied.

At that moment, Dr Farrow re-entered the room, and Sheldon hastily put down the wand, his face flushing pink.

The doctor smiled. "Taking another look were you?"

"Uh, I was just…"

"Don't worry about it." She winked. "I didn't see you! Now, I've spoken to Julie the midwife, you're all booked with her. Your first appointment will be next Monday at midday, just to meet each other and so on. Your next appointment with me will be at 8 weeks, so three weeks from now." She handed Amy an appointment card. "Just to check everything is still going good, and if you have any problems, don't hesitate to call me or Julie. Also, because you carried twins before, even if you didn't give birth to them, it's still highly possible to fall pregnant with them again since twins run in your families. Also you're just over 30, and because you have irregular ovulation, sometimes that means you can hyperovulate, so two eggs got fertilised at once. There's your information pamphlet, and we'll see you in three weeks for your check-up." Dr Farrow smiled. "Any questions?"

Amy and Sheldon looked at each other.

"Um…What can we do to ensure that Amy stays pregnant this time?" Sheldon asked.

"That's in your pamphlet too, but in this case, be super careful with everything; so if you have sex, don't be too rough, eat healthily and avoid all foods that are listed on page 11 of the booklet, drink plenty, rest plenty and just steer clear of cigarettes, drugs, alcohol…The usual, but stricter this time."

"Thank you." Amy grinned.

"You're welcome, and congratulations. See you in three weeks!" Dr Farrow smiled as Amy and Sheldon left the small room and made their way out to Amy's car.

"I like her; she seems to know what she's doing!" Sheldon commented.

"Ooooh, have a crush do we, Sheldon?" Amy sang.

"Be realistic Amy! I love you and you're bearing my progeny. I wouldn't want to look at another woman." Sheldon replied.

"And the same applies for you!" Amy said, turning to face him. "Look, I know that hearing I'm five weeks along instead of three was a bit of a shock, I was shocked too! But there was no need to insinuate that I was unfaithful to you. You know it's always been you." She said, softly and almost sadly. "Sheldon, I don't want anyone else. Sure, you can be annoying as hell to some people and heck, even to me, but I wouldn't change you for the world, and I wouldn't even glance in another man's direction. I'm married to you, I want children with you. I love you!"

Sheldon hung his head. "I'm sorry Amy."

"It's okay." She sighed, "Who cares anyway? We're going to be parents!"

"Maybe." Sheldon nodded, "If everything goes to plan."

"It will, because we're the Coopers. We can get through anything together, right?"

"Well, past experience says that we can, so technically…"

"Oh my God, Sheldon, get to the point!"

"Yes. We can."

The two of them grinned excitedly and wrapped each other in a tight hug, before getting into the car and driving home.

..

Once they arrived back at the apartment building and ascended the stairs, Amy turned to Sheldon.

"I still don't think we should tell anyone about the babies just yet." She whispered. "Until we know for sure that it's safe. Let's say at 12 weeks."

"But Amy! You know I am awful at secret keeping, and we have another seven weeks until then! That's almost two months." Sheldon protested.

"Please Sheldon?" Amy pleaded.

"Alright." He agreed. "I'll just avoid them for seven weeks."

Amy frowned. "Good plan."

They unlocked the door and stepped inside, to find Leonard sat in the chair that faced the door.

"Oh hello guys…How are the babies?" He asked.

Sheldon and Amy froze, and it felt as though time was standing still.

One question ran through both of their minds at that moment;

How did he know?!

..

A/N: I'll probably get flamed and questioned to hell again for this chapter, so I'd like to just say beforehand that I did research the whole twin pregnancy thing before writing this chapter, like I do when I write anything science or medical-related. ( twins/chance-of-having-twins-again-after-one-set-o f-twins-190634) I looked on some other websites too, and apparently it is possible. So blame them, not me ;) Please refrain from flaming, I am not going to re-type this or delete my story no matter what anyone says, so you'd be wasting your time. Nobody said you had to read it, and it is fiction after all, so of course it will be OOC! :) Thank you to those who have been following and reviewing etc. it really means a lot that you enjoy it! Next chapter coming soon! X
