Hello everyone! This is my first Vampire Diaries fanfiction story so I'm pretty excited, because I've wanted to write one in a while now. Anyways in this story- Caroline is a only half vampire and Tyler is indeed a werewolf. Caroline was fed vampire blood by Damon at the hospital, but before Katherine killed her – Bonnie did a spell to make sure Caroline didn't turn into a vampire.(Let's all pretend there is a spell for that); Caroline knows about all the vampire drama and about the witches. When Tyler turned into a werewolf, he imprinted on Caroline, making her his mate. Also, this is like towards the end of senior year. I think that's all, so yeah enjoy and don't forget to review our opinion or any questions!

"It isn't possible..."
-

"Sorry guys, I can't tonight. I haven't been feeling well and I've been on edge lately…" Caroline confessed. The three best friends were in Elena's bed discussing plans. She was trying to get out of Elena's sleepover that night. It's not that she was avoiding them. She wanted to be there for her friends, but now didn't seem like the right time.

It was true; she has been on edge lately. Lately she hasn't been herself, and she doesn't know what could be the cause of it. She's been getting sick for the past few months and she didn't know why. She wanted nothing more but to tell Tyler, her beloved boyfriend. But she was too worried that he would worry. It's enough that he has to worry about his werewolf pack every month, making sure they were secured somewhere in town and made sure no one killed anyone on the full moon. It was dangerous. Caroline has always been there by his side as he shifted to a wolf on the full moon. He begged her to go away, that he didn't want to hurt her. But she didn't care.

She wanted to be there comforting him, assuring him that he wouldn't hurt her. She loved him and trusted him. He also had to worry about Caroline being protected. He had finally got a few werewolves from his pact to accept her and his place in life- which was being together. She was Tyler's happiness, his salvation. He was the only thing real in her messed up world. Before the vampires, the werewolves, and the witches- everything was simpler then it seemed. Growing up, finding out who you are, stuff like that.

Now- everything wasn't so simple. It didn't feel real. And sometimes, Caroline wondered if this was all just a weird fantasy. The world she once knew was nothing like the one she lived in now. When she was 7, she was scared of the make-believe monster under her bed. What she should have been scared of was if a vampire/werewolf was under her bed. Now she's 18 and she still can't live with the truth. The unsafe town she grew up in with her friends. How she had to live with the fact that she was half vampire because Damon fed her his blood, Bonnie did a spell to prevent her from turning, and then Katherine killed her. Now she has vampire powers, craves blood, but still ages and is half alive.

The spell had only half worked, because Bonnie wasn't that skilled to do a spell that powerful.

Tyler had all this stuff on his mind, too. He too has to live with the fact that he was a werewolf, even if he did get used to it.

So Caroline decided not to bother him either. She didn't want to throw her problems to him either, when without doubt she should inform him.

She decided against going to the Salvatore brothers, since they might know something from being around for years, but hoped it was nothing. That she will get better. But it only got worst. The massive headaches, the stomach pains, the constant feeling nauseous- it was getting worst. She finally lost hope of getting better and decided maybe it was time to notify someone of the sudden illness. She didn't know if she should tell her best friends though. They were too busy dealing with their vampire drama. Besides- if she needed anyone at this moment- it was Tyler. He was getting suspicious after witnessing her throw up for almost 10 minutes in his bathroom. She had lied it was nothing, but her being his mate—he had seen right through her little lie. He wanted to take her to the doctors or something but she refused to.

"Caroline, what's wrong? I've noticed something's changed." Bonnie stated, reaching for her friends hand.

"You know you can tell us whatever's bothering you." Elena assured the blonde. Caroline sighed and turned to look up at Bonnie, who had a surprised and distant expression.

"Bonnie?" she called out.

"Bonnie what happened?" Elena asked the witch. She was silent for a minute, finally letting go of her hand and stared at it.

"H-her hand… when I touched it I heard…" she paused, "or felt something…" she confessed.

"What was it?" Caroline began to get worried.

"A heartbeat." Bonnie said.

A heartbeat? You can't be serious.

Caroline found this absolutely ridiculous. A Heartbeat? Really? She got worried for nothing, if anything she found this quite amusing.

"Are you serious? Come on, Bonnie! You've got to be kidding me! If you haven't noticed- I HAVE a heart! And it BEATS!" she laughed. Bonnie sighed and looked Caroline dead serious in the eye, telling her to knock it off.

"No, Caroline. I meant I heard two… two hearts. Beating."

Caroline was shocked. Two hearts? What did that even supposed to mean?

"Are you sure? Maybe we should go to Stefan a-" Elena was cut off by Caroline when she realized what she was referring to do.

"No! Stefan and Damon are not to know about this. No one is." Caroline demanded.

"What exactly is "this"?" Bonnie asked; Caroline didn't know the answer though. What was she trying to hide? That she was sick? That something was wrong? Or was she scared to find out the truth about her illness and sudden two hearts beating?

Or maybe all of the above.

"Again- what's wrong? What are you trying to hide?" Elena asked gently, with suspicion filling her eyes.

"Ugh- it's nothing." she lied. But she sucked at lying.

"Caroline, we all know you're a horrible liar so tell us the truth. Don't be afraid- we won't judge." Bonnie defeated her.

Caroline sighed in defeat.

"Okay fine! It's just- I've been so moody lately, and I keep feeling the urge to throw up all the time and I don't know why but I've been craving blood more than ever which I shouldn't because I'm not even like full vampire!" Caroline said quickly in a ratio of 4 seconds. She breathed deeply to catch her breath.

"Well… I understand that being a half vampire your emotions heighten, making you feel a little more insecure then before. But the craving for blood you should be able to control…you have been controlling it, right?" Elena and Bonnie looked at her suspiciously.

"Yes! Don't worry, I haven't killed anyone and I'm not going to! It's just I feel like I want it…maybe even need it." Caroline confessed, almost looking ashamed. "OH and I am NOT insecure, Elena!"

They all laughed at her sudden outburst, until they went back to being serious.

"This still doesn't explain anything. Or the throwing up." Bonnie spoke up.

"Maybe you should see a doctor or tell Stefan. That isn't normal." Elena gave opinions that she didn't want to look in to.

Definitely not going to ask Stefan, but what about a doctor? She can always compel them to tell her what's wrong. Stefan probably doesn't have a clue to what all this could be either. But if the doctor doesn't work, she will consider going to Stefan.

"Fine, I'll see a doctor. If that doesn't work – I'll tell Stefan." She sighed and stood up from Elena's bed.

"Wait- What about Tyler? Are you going to tell him?" They looked at her for an answer, probably expecting her to say yes.

"Ugh, I don't want to worry him. I think I should just wait until I find out something." She said; they nodded in agreement before Caroline informed them that she would talk to them after the doctors. She turned on her Fiesta car and buckled up turning on the car, before getting a text from Tyler.

From: Tyler
11:04 am

Babe, where are you? We still hanging out at your house later?

Shit. She totally forgot about their plans. She came up with a solution and replied to his text.

To: Tyler
11:05 am

Sorry baby, I was just at Elena's. I need to go help out a friend with ideas for a fundraiser, so I will be home around 12:45, okay? Btw- I miss you 3

Sure, she lied about seeing a friend. But it was true- she did miss her boyfriend dearly. All the weird things happening to her have made them a bit distant, and it was completely her fault. She just didn't want Tyler to be all worried about her health. Her phone rang and it was a text from Tyler.

From: Tyler

Sounds perfect, baby. Aw I miss you, too sweetie. I gtg help Spinner get new chains for Wednesday, so ill see you soon. Love you 3

She replied with a simple "I Love You, too 3" before she was on her way to the doctors.

When she finally arrived after 15 minutes, she parked her car in the parking lot and walked up to the entrance of the small building. She walked up to the lady in the main office and told her she was here for a checkup.

"Sign in here and go wait in the waiting room for your name to be called." The desk lady said, handing her a paper and pen. She thought about what she would say/do while she signed in for an appointment. She returned it to the lady and sat in the waiting room, hoping everything was fine.

After a few minutes of name calling, she finally heard hers.

"Caroline Forbes."

She got up and walked through the doors and saw her Doctor.

"Hello, Caroline. Nice to finally see you, it's been almost two year since I've last seen you. Follow me," Dr. Stuart led her to an empty room with low music on.

"It's nice to see you too, Doctor." Caroline replied.

"You can take a seat right there. How have you been? I see you're here for a checkup?" He asked.

"I'm good, and yes."

"What's wrong?" he asked.

"Well, that's what I'd like to know. I've been throwing up a lot for the past few months, I'm having these massive headaches, and… weird cravings. Also I've been moody lately." She said.

"Alright, well – let's take a look at your vision, and check how your breathing is doing." He got one of those tools doctors use to check on people's eyes. As soon as he came close to her, she decided to compel him just in case. She looked him deep in the eye and said - "You won't tell anyone I am half vampire, and you will ignore anything suspicious about it. You will continue on checking me and tell me what's wrong." and then let go of him.

"Okay, let's check your heart rate." He shacked his head and moved on to put on the headphone like tool and pressed it to her heart and asked her to exhale and inhale.

As he moved a little lower to her stomach, he put a confused look on.

"Is everything alright?" she asked.

"Yes, but I heard another heartbeat." He told her.

So Bonnie was right… but what does that even mean?

"Come, I need to check your abdominal section." He waited for her to stand up, and she followed him to a room with a monitor, and told her to lie down on the doctor chair, that was reclined for her to lie down.

"Okay, I need you to lift up your shirt a little so I can put some of this gel on your abdominal. It might be a little cold." He assured her. She did as he said and cringed at the cold goo on her lower stomach.

"That's really cold." She giggled.

He got the stick monitor and moved it along where the gel was, obviously looking for something and then he stopped.

"Ah, there It is." She was confused.

"What? Where is what?" She asked.

"There is your baby, look at the monitor."

She turned her head in more confusion to the monitor he was pointing to and was shocked to see what was on it.

Something that looked like a growing fetus.

"Whoa whoa whoa… I don't understand. Why is there a fetus inside me!" She was freaking out.

"You're pregnant." He told her.

She was speechless. She couldn't move or speak or think. It was all too much to take in. After about a few minutes, she finally found her voice.

"W-wha...uhh…how…PREGNANT?" she burst, "How is that even possible? It isn't!"

But then it hit her, it was in early February. When they were at one of his old Family Lake houses and stayed there for the weekend alone. She remembered that they forgot to use a condom. It could be possible.

Shit.

"Well, your about 3 ½ months pregnant. That explains the nausea and mood swings, you have all the symptoms. You also had gained a few pounds. Not enough, but I'm guessing it has to do with you not eating much of what you crave. " He said.

"So now what do I do? God, I'm pregnant and I don't know what to do! I don't even know if it's possible."

"Well I don't know about that. All you should do is take care of your health, and hydrate yourself. Oh and whatever your craving- eat/drink it. The baby wants it."

After compelling him to forget about ever seeing her for the checkup, she walked to the front office, picked up a free pregnancy book, and then walked to her car. She sat in it in silence before looking at the book.

"Pregnant: Beginners edition: What to know"

She concentrated on the word 'pregnant'.

"God, I'm pregnant." She murmured before receiving a text message. She searched her purse for her phone and when she found it she saw missed call from Tyler. She decided to call him back and waited a few minutes for him to answer.

"Hey babe" he answered

"Hey I'm on my way home now, are you close?" She asked.

"Yeah, I'm all done. So I should be there in a couple of minutes." He informed her.

"Great, see you there. Love you" she replied.

"Love you too." He told her back before hanging up.

She stared at her phone for a minute. Fear finally rising inside of her.

What am I going to tell Tyler? Oh god… what if he hates me? Ugh, I have to tell him.

She got checked her inbox and saw she had a unread message from Bonnie.

From: Bonnie

Everything okay? I'm with Elena btw.

Caroline sighed with frustration and texted her back

To: Bonnie

I'm pregnant…

She waited a minute for her to reply, and when she didn't- she got a little worried. She drove home and as she parked her car she heard her phone, and checked her message.

From: Bonnie

Omg! Tell us everything later when you're not busy, just pass by Elena's later.

She replied with a simple okay and grabbed her purse before shoving the pregnancy book inside. She unlocked her front door and closed it after entering. When she reached her room she sighed and fell on her bed, throwing her purse to the corner of the bed. She sighed into her pillow before hearing something outside her window. She ran to the window to see what it was, and sighed in relief when she saw it was Tyler.

He opened her window and climbed in.

"Tyler, you scared me!" she lightly slapped his arm. He chuckled at her cuteness and kissed her lightly on the lips, his palms caressing both her cheeks. He pulls away and bumps their foreheads together; she already missed the feeling of his lips on hers.

"So now I scare you?" he whispered to her. She giggled lightly and whispered back,

"I thought there was a scary monster trying to attack me."

He laughs at her confession and says, "Caroline, I turn into a monster every month and I try to attack you."

"That's different, you wouldn't hurt me." She says, her hand now stroking his cheek. He brings her into a tight hug and whispers in her ear with a little frustration in his voice.

"You can't be so sure."

She sighs and pulls away to look him in the eyes and says, "Let's not discuss that anymore. I haven't seen you since Friday and I've missed you so much."

"Ha, can't get enough of me, huh? It's been one day, babe." He chuckles, but sees her face turn mad.

"Asshole." She spits out, and turns around to no longer face him and takes a seat on her bed, arms crossed.

"Aw, babe. I didn't mean it in a bad way. I've missed you too." He said and took a seat next to her, only to be facing the back of her head. He brings her from behind closer to him and kisses her neck. She smiles shyly and turns so that she's facing him now and brings her lips to his.

He moans a little in her mouth and lays her down, knocking down her purse to the floor.

He smiles against her lips and pulls away.

"Sorry I knocked down your purse." He turns to look at all the items that have fallen out of her purse now scattered around. As he is about to turn back to her, he grabbed something that caught his attention.

He got off the bed and reaches for it.

Shit! Caroline thought, sitting up to kneel on the bed.

He examines the book in his hands and turns to Caroline.

"What's this?" he asks, but he already knows what it is.

"Uh…a pregnancy book." She spoke, scared for what's coming next. He saw the nervous expression in her eyes.

Why would she be nervous? He thought.

"Why do you have a pregnancy book?" he asked, wondering what could be the reason.

She didn't speak.

"Caroline?" he called, "What's going on?"

She looked him in the eyes with a worried expression. She looked down at her knees and sighed.

"Tyler, I'm pregnant."
