A/N: First off THANK YOU EVERYONE! Who reviewed and alerted and favorited my story words can not describe my gratitude, so thank you. Also I do not know much about pregnancy since I have never been so if I say something wrong I am sorry. So I have been doing research and well I know you can't hear the heartbeat or see it on a sonogram at the stage Blair is at but for all literary purposes I may have changed that only because I liked my chapter title and seriously could not get myself to change it. So hope you enjoy chapter 5 is already written and I'm going to update my other story today as well.

Chapter 4: The Beat of Our Heart

2 days later…

"Blair," Chuck called to her from the kitchen, they gave Dorota the week off so they could spend sometime together, figuring things out, "we're going to be late for our first Doctor's appointment if you don't hurry up," he smiled, he just couldn't seem to wipe it of his face, it made his face feel weird, his cheeks hurt he knew it was because those cheek muscles were not used to this smiling thing.

Blair finally emerged from her bedroom, where they have spent the past two days,

"I'm coming," She laughed as she started walking towards him, but suddenly stopped and looked at Chuck with the color draining from her face.

"Blair what's wrong you like your about to be sick," Chuck said with concern quickly walking from the kitchen towards her.

"I'm going to be," she said quickly before darting into her bathroom.

Chuck followed her, this wasn't the first time Blair had suddenly become sick, he knew it was morning sickness , he just never knew how sick women actually got from it, the past two days at any given moment Blair would lose color and become all pale and clammy and run to the bathroom, though Chuck would never do this for anyone else, he followed her into the bathroom and held her hair back as she proceeded to vomit into the toilet, he rubbed her back , because after all it is partly his fault she is sick to begin with.

"I'm right here," he said soothingly as he rubbed circles into her lower back. He took out his cell phone and called the Doctor's office to inform them they would be late.

"Dr. Montgomery's office, How may help you?" A receptionist answered the phone.

"Yes, It's Chuck Bass calling about my girlfriend, Blair Waldorf," the word girlfriend didn't seem fitting it seemed right but Blair will soon be so much more, "We have our first appointment in forty-five minutes, we will be running a little bit late, Blair is having another spout of morning sickness," He told her.

"Oh yes no problem, Dr. Montgomery is running a little bit late, and for Blair's morning sickness I suggest some ginger ale and saltines to calm her stomach down," the receptionist told him.

"Okay thank you so much," Chuck said before hanging up the phone, just as Blair finally stopped being sick.

"ughhh," Blair moaned as she looked up at Chuck who was sitting next to her on the bathroom floor.

"Feeling better?" Chuck asked her with a raised eyebrow.

"Yeah," she sighed as she closed her eyes to compose herself, "do they know were going to be a little late?" she asked him.

"Yes, I called them," he chuckled, knowing she probably wasn't paying attention to anything other then being sick, "they said ginger ale and saltines would help do you want me to get you that, I'll run out myself and go find it for you," he said with a slight smile.

"No you don't have to do that I think I'm good right now," she smiled.

"Well in that case let me help you," he said getting up from the floor and grabbing a wash cloth from the rack before turning on the sink and putting it under some cool water to make a cool compress for her, he then bent down next to her and started to carefully pat her face with the cool cloth to help clean her up.

"Why are you doing this being so sweet and kind and caring," Blair asked him tiredly from the ground.

"Because I love you and if I could I would do all of this for you," He smiled at her as the color in her face started to come back.

"Chuck Bass would never want to do this for anyone," Blair let out a light laugh.

"For you Waldorf you can't even begin to imagine what I would do for you," He smiled and brushed a piece of hair out of her face. His response instantly made Blair smile and cheeks blush.

"Is the so?" she asked him with a smirk.

"It is," He smiled and helped her off the ground, and kissed her head.

"Ew, Chuck I smell awful and like throw up," Blair grimaced.

"I can't help it your so beautiful and sexy," he winked at her before she shook her head still in disgust as she took out her toothbrush started to brush her teeth.

"I'll be waiting for you by the elevator," he said laughing at Blair's reaction as he walked out of the bathroom.

45 minutes later…

Blair was wearing an examination gown sitting with her legs hanging of the examination table. Chuck had never been to an OBGYN's office before and of course like any first time expectant father he was nervous, pacing around the small room with posters and models of Uterus' , Ovaries , and Fetuses.

"Chuck," Blair said sternly.

"Huh?" Chuck said snapping out of his thoughts.

"Stop pacing your making me nervous," she glared at him. He instantly stopped and pulled a chair over to her.

"I'm sorry," he sighed as he took her hand in his and brought them to his lips and kissed them, "how are you doing?" he asked her realizing he was focusing on himself when his focus should be on her.

"Nervous," she laughed uncomfortably.

"Well as far as we know your healthy the baby should be healthy and until we learn other wise we should be fine and if something isn't right we will do whatever we possibly can do to fix it and at the end of the day no matter what I will be hear with you holding your hand," he kissed her.

"Wow," She smiled, "when did you grow up?" she laughed.

"I think it happened when I almost lost the most important thing in my life," He smiled.

Just then the Doctor walked in.

" I'm Dr. Montgomery, and how are we doing today Ms. Waldorf and Mr. Bass?" Dr. Montgomery asked the young couple.

"Please call me Blair," she smiled politely.

"And please call me Chuck we don't have to be so formal here," he shook her hand.

"Well you took a home pregnancy test and we drew some blood?" she asked Blair.

"Yes I did the test was positive and they took my blood as soon as I changed into the gown," Blair replied.

"Well I have the results right here," She said to the young couple with a smile.

"And?" Chuck asked nervously.

"Chuck," Blair glared at him for interrupting.

"Sorry, what does her results show?" Chuck asked calmly.

"Well your home pregnancy test was correct you are having baby," Dr. Montgomery told them. Both Blair and Chuck instantly had smiles on their faces as they looked at each other so in love. " So Blair when was you last menstrual cycle?" the Doctor asked Blair.

"um I would say about seven weeks ago?" Blair said trying to think back.

"Ok well if you don't mind please put your feet in the stirrups so I can take a look down there," the Doctor said motioning to Chuck to get up off her chair. And Chuck started watching what the Doctor was doing.

"CHUCK BARTHOLOMEW BASS!" Blair shrieked

"what?" Chuck looked at her confused.

"You will not look and stand over by my head," She hissed.

"It's not like I haven't seen it all before honey," He gave her a devilish smirk.

"You will never see it again if you don't get over here right now," she said with a sweet smile.

"Fine," he huffed.

"Well at least I know not all of the Chuck Bass I know and love is fully reformed," She laughed right before she quickly tensed up as the doctor started examine her.

"That's not face you make when your with me," he whispered huskily into her ear, Blair shot him a death stare for that comment.

"Well everything looks good you seem to be five weeks along" She said while wheeling in an ultra sound machine, "so you should be due sometime in February so let's do a sonogram," She said as she god her wand out, "Okay Blair now this might be a little cold she said as put some of the gel on to her stomach, "you and Chuck should watch the screen," she said moving the wand on Blair's lower abdomen.

Blair and Chuck were holding hands with their fingers laces together, intently looking at the screen. Suddenly something popped up on the monitor.

"Blair…Chuck," Dr. Montgomery said, "Do you see the little thing fluttering across the monitor," She asked them.

"Yes," they both nodded in unison.

"That little thing fluttering is your baby's heart beat," She told them, "I'll give you guys a moment alone," She said as she walked out and left the couple looking at the monitor.

Blair and Chuck both had tears running down their face as they looked at the screen and then at each other.

"I love you," Chuck whispered.

"I love you too," she whispered back as they kissed.
