I never know why. I only know who. (AU)

Chapter 15

They were back at school the next Tuesday, and already in the sixth form. That meant they no longer had to wear the itchy school uniform, and everyone loved it. It was suddenly colourful in their year. But they were told in the first hour that the girls had to have decent cuts on their shirts, and no butts, boobs or stomachs were allowed. Clara had no idea how people still groaned at that, believing they would have ever been allowed. It was common sense after all.

She was with John in both History and Chemistry, so she didn't feel too alone in them classes. Mr Simons had started off the lessons by letting them sit anywhere they wanted.

John and Clara ran to the centre of the room, but right at the back where they were most alone. The other two couples in the room ran to the side benches, making Clara laugh.

The first thing Sir said to the whole class, as he walked down the aisles, was, "I don't care if you don't work. If you fail, it's not my life I'm ruining. So you can sit where you want and do what you want. But, If I catch any hand-jobs going on at the back of this room, then I will make sure you never live to see the light of day."

Clara's jaw had dropped open along with John's, and she removed her hand from John's thigh, which she hadn't even realised was placed there.

Even though there were two other couples in the class, they both knew the sarky comment was directed to them, which was emphasised by the small wink Sir gave as he walked past, before going to the front of the class to start up the lesson again.

Friday lunchtime. The moment when Clara felt her entire world turn upside down.

She was sat in the sixth form lounge, John, Amy and Rory one her one side, with Olivia and Louise facing her.

She wasn't really listening to what Olivia was saying, tuning out to pay attention to watch John was saying to Amy. She found his voice much more interesting, although she tried to her best to look like she cared.

"Clara?" Olivia called, making her turn her attention back to her.

"What?" She'd asked angrily, suddenly feeling ashamed as John turned to check she was okay from her loud tone. She'd forgotten how easily she could be rude to people if she wanted to.

"I asked if you had any paracetamol?" She repeated, watching Clara as she suddenly paid attention.

"No, sorry. Why?" She replied, leaning over to Nina as she moved away from John.

"Because I have cramps and it's killing me. Ask Amy for me?" Nina begged, looking over to the redhead as Clara leaned back against the chair she was sat in.

"You!" Clara argued, watching as Olivia was stupid. "It won't kill you." Clara mumbled, looking away.

Olivia stood up out of her chair to walk over to Amy and decided it would be best to ask her as loudly as possible. Clara rolled her eyes to Amy as the girl looked her way.

"Sorry." She mouthed, making Amy dig through her bag for some pills.

Clara thought about the situation for a moment, wondering why she had no pills on her. Usually she carried some, just in case she ever needed them, which she rarely did, or usually for Nina or Kelsey.

During her thinking, Clara suddenly froze. Period pains. Periods.

She thought back to the last time she'd had one, but she couldn't think. The colour must have drained from her face, but luckily no-one noticed.

In a panicked daze, Clara slowly began to dig through her bag for her phone, pulling up the calendar she had on there.

She scanned through the dates. Her last period had been a week before the prom. She had left for America a week after prom. So she should have had one in her third week in America.
