Please, do, enjoy the final story in my series.


Rose Tyler opened her eyes, sighing in content, blinking slowly as she woke from the depths of sleep that had consumed her. Rubbing the sleep out of her eyes Rose rolled over, focusing her brown eyes upon the man who lay sleeping next to her, his chest rising slowly as he took deep breaths. A slight smile traced her mouth and with her right arm reached up to trail her fingers lightly over the Doctor's face, leaning forward ever so slightly to press a kiss to his cheek. Memories of the last few months roamed throughout her head.

She did not have long to wait before the Doctor woke from his slumber, as the tender kiss she had planted upon his cheek, had been enough to stir him.

"Good morning," Rose whispered softly, leaning in close, "Did you have a good sleep?"

"Yeah, I did," he smiled in reply. He slipped his arms around her, pulling her closer to him.

Rose leaned up slightly, his lips catching hers in a gentle kiss, but before she could pull away it had turned into passionate one and she found her body trembling as he pushed himself closer to her. Within seconds she was pinned beneath his weight as he rolled on top of her, never halting the kiss.

Her hands, which had been resting on his shoulders, moved down his bare back, and she could hear him moan softly against her lips. Finally they broke apart and he moved off of her. She tracked his movements as he climbed out of bed. He wore a pair of pyjama bottoms which he had acquired (and kept) from Jackie when he had regenerated. Picking up his usual blue suit, he gave her a quick smile before disappearing into the bathroom. Leaning back on the pillow, Rose felt her mind wander aimlessly back into the past.

Five months ago had been the first time she and the Doctor had slept together. It had only been after the red dragon incident that they had finally come together, though it had taken Rose a long time to accept that the whole incident in question hadn't been entirely her fault. Until she had accepted that fact, then their relationship hadn't progressed that far, but when she had, the relationship had become something more.

They had slept together three times since the first time. Though the Doctor barely slept, he still stayed with Rose during the night. He liked watching her sleep, his mind wandering over the past. He liked watching her wake in the morning. More to the point, he wanted to spend as much time with her as he possibly could. Rose loved waking in the morning to see him smiling at her.

A smile pulled at her lips as the Doctor emerged from the refresher wearing a white shirt, with a blue jacket over the top. He had on a pair of matching trousers and red trainers.

"Not up yet, Rose Tyler?" he asked cheerfully.

She shook her head. "The bed is too nice. You can come and join me if you want."

The Doctor's face reddened and he hastily retreated from the room causing Rose to chuckle. No matter how much he loved her, Rose realised that the Doctor would probably never be comfortable with some of the things she mentioned. Rolling out of bed Rose pulled of her night dress, picked up jeans and a t-shirt, went into the refresher, washed and dressed. Brushing her hair and applying a bit of make-up she left the room to seek out breakfast.


"Yeah, Martha?"

"Are you feeling alright? You've barely eaten anything for the last three days…" she trailed off, unsure of how to press her concerns.

Rose shook her head. "I just feel ill in the morning. I can't keep my food down. I don't know what's wrong with me."

Martha bit her lip. "I think I know why you may be feeling like this." She offered.

Rose waited silently for her friend to tell her, keeping her gaze upon the other woman.

Shuffling her feet Martha spoke again: "I think you're pregnant."

There was utter silence between them until it was broken by Rose.

Rose's face blanched. "What?"

Martha nodded. "You've been throwing up in the morning…could be morning sickness…it occurs around the three month mark."

Rose's eyes widened as she considered the facts. She had missed her period a month ago and she was due for another one…but the sickness did make sense…after all she and the Doctor had first slept together five months previously. The second time they had slept together had been two weeks later, but that didn't fit either. On the two month mark, they had celebrated. The timing was right. And we didn't use protection…

"I think so too." She replied.

Together, Rose and Martha sat in an uncomfortable silence in the bathroom, waiting to discover whether Rose was with child or not. In her hands Rose held the pregnancy test, waiting for the results to show. Martha laid her hand on Rose's arm. "You'll be alright."

"Do you really think so?"

Martha nodded. "Of course I am."

She could see Rose wrestling with herself. She wanted to ask her something but didn't know what to say. "You can ask if you want."

"You're sure?"

"I'm here to help you Rose. If I didn't want to, I wouldn't have bothered telling you what I thought. You can trust me."

"I know," Rose sighed, and Martha could see apprehension in her gaze, "If I am pregnant, will he want it? What if he doesn't? What if he's horrified and decides to drop me off on some random planet and leave me there? What if he rejects me?"

It's too soon for them, Martha realised. Over the months she and Mickey had watched the two come slowly together. And then they had gone away for a two month break and when they returned to collect herself and Mickey from the parallel earth their relationship had changed, especially when they had started to share a room.

Still, both of them had agreed it had been inevitable, that it would come at some point, but neither of them had expected Rose to become pregnant so soon.

If she is.

"Rose, the Doctor loves you. Anyone can see that. You are the most precious thing to him and the fact that you may be pregnant won't change that. He wouldn't abandon you ever. You two have something special that cannot be denied. You're meant to be together. I don't believe that the Doctor would dump you on some planet just because you may possibly be pregnant. He loves you too much to want to harm you."

Rose smiled slightly and rested her head against Martha's shoulder. Martha knew her friend was worried, concerned about what the future may bring. But there was one thing Martha Jones was sure of: the Doctor would never abandon Rose Tyler.


Two Days Later…

"You've been a bit distant." The Doctor commented as he walked into the room he shared with Rose.

She jerked her head up, moving her hands away from where they had been laying on her stomach. Shortly after Martha had effectively diagnosed her symptoms Rose had got the Doctor to stop off on Earth so she could buy a pregnancy test and in private she had taken the test. It had been positive. She was pregnant. And it frightened her.

"Is there anything you want to tell me?" he asked, sitting beside her and taking her hand in his.

Rose bit her lip considering what to say. Should she tell him? How would he react? Would he tell her he wasn't ready to be a father? I can't tell him, not yet…I need to see my mum. Yes, that was the best thing. Her mother would know what to do. She looked up, noticing for the first time that he was staring at her with a concerned look on his face.


She shook her head. "No, there's nothing."

"Are you sure?" he didn't sound convinced.

"I'm fine." Rose replied, but thought: Apart from the fact that I'm pregnant with your child and I don't know what to do.

He started to get up, but she grabbed his hand. "Doctor…I need to see my mum…can we go and visit her?"

The Doctor nodded. "Alright. I'll go and set the co-ordinates."

As he left she whispered under her breath: "Thank you."
