Donna looked at her reflection in the mirror, then back at the box that was sitting next to the sink. She was sure it hadn't been there before she had stepped into the shower, but it was definitely there now. She cast a glance upwards, and the lights dimmed slightly. The TARDIS did provide for all of their needs, and she supposed that meant she needed this. She picked up the box, gingerly, and read the words on the side. "Pregnancy test." She put the box down quickly, and looked back at herself in the mirror. Did the TARDIS know something? She tried to count the days. It was so easy to lose track, travelling. She picked up the box again, started reading the instructions on the back, tried to pretend her hands weren't shaking.

The Doctor burst in. "Donna? Aren't you dressed yet?"

She turned, startled, and quickly put the box behind her back. "Oi! Remember knocking?" she asked, hoping he hadn't seen the box.

"What d'you have there?"

"What? Nothing," she said quickly.

He reached around her as she tried to evade his grasp. "What are you hiding?"

"Nothing!" she protested, but the box fell from her hand and he snatched it up.

"Aha!" he said. "What do we have here?" He read the side of the box, as Donna felt her face flush. "When did you get this? Why did you get this?"

"I didn't! It just appeared on the countertop." She took it from him, gently prying his fingers away.

"D'you think--" he said, a grin spreading across his face.

"Won't know until I take the test, I suppose," she said, pushing him back toward the door and closing it behind him. She tried to focus on the instructions.

"Donna?" he called through the door.

"This will be easier if you don't talk to me for a minute," she said.

"Oh, of course."

A few minutes later, the completed test on the counter, she opened the door to find him still standing there. At least he had stayed quiet.

"Well?" he said, his voice a little higher than normal.

"Won't know for two minutes," she said.

"Oh," he said, his face falling. "Should you sit down or something?" He took her hand, and she hoped he wouldn't notice it was still trembling a little.

"Might as well," she said. Two minutes seemed like a very long time. She let him lead her over to the bed, where he sat down next to her, keeping hold of her hand.

"So," he said.

"So."

"Are you feeling alright?"

"Nervous," she laughed. "But fine otherwise."

"Good, that's good," he said.

"You?"

"Nervous," he admitted. "But in a good way," he added.

"Good." She turned his hand over in hers, traced his palm. "I'm glad we're finding out together," she said.

"Me too. Either way."

"Yeah, either way."

" 'Cause if you're not, y'know, we'll keep trying."

"Of course," she said. "We've only just started."

"Right."

"Right." She looked up at him. "Do you think it's been two minutes?"

He grinned, "Yes, just now."

"I'm a little afraid to look," she said, as she felt butterflies in her stomach.

"Me too."

"Together, then?"

"Together," he agreed, as he stood and helped her to her feet. She clutched his hand a little harder as they walked back to the bathroom and stood in front of the counter. She kept her eyes on his. "One two three go?" he said. She nodded.

"One, two, three," he said, and they both looked down at the test. A plus sign showed clearly in the indicator window.

"Plus means positive, right?" he asked. Donna nodded, a lump in her throat. She looked back at him, to see a huge grin on his face. She felt a matching smile begin at the corners of her mouth, and then he was kissing her, holding her tightly to him. He lifted her from the floor, then set her down quickly as she laughed. The lights dimmed, then brightened again.

"How did the TARDIS know?" she asked, his arms still loosely around her.

"No idea. But I think she's pleased."

"She won't mind having a little one running around?"

"No, I don't think she'll mind," he said. Donna thought she heard the faint strains of a lullaby in the background hum of the TARDIS as he kissed her again.
