"And how do you know that for sure?" I asked, watching her closely.

Yolanda glanced at me, then quickly said, "Because I just had my period a couple days ago."

She was lying, obviously. Sylvia tilted her head. "Then something is definitely not right. What if there’s something growing inside, like a cyst or... worse?"

That actually shook her a little. "Fine, whatever," she muttered. "I’ll get it checked out later."

"I’ll go with you," I said quickly. "I haven’t had my period in over six months and my stomach’s getting kinda big too. I should probably get checked out."

Yolanda froze for a second, then immediately changed her tune. "Actually... on second thought, finals are coming up. Neither of us is feeling sick or anything. Let’s not waste time going now. We can go together after the exams."

"Yeah, alright. After finals it is," I replied. After that, she barely let me out of her sight. She stuck to me like glue, always hovering nearby.

It just so happened that I got my period that day and stupidly, I forgot to bring a tampon. I panicked a little. To keep anyone from noticing, I rushed straight back to the dorm as soon as class ended.

"Trixie, what’s the rush?" Yolanda called out.

"I’ve got a stomachache. Need to use the bathroom," I said, trying to play it cool.

She frowned. "Why not use the one in the teaching building?"

"It’s... loud diarrhea. Super embarrassing," I muttered.

She didn’t look convinced, but I didn’t wait for a reply. I made a beeline for the dorm, with her trailing behind like always. I didn’t even get a chance to grab a tampon.

With no other option, I ran straight into the bathroom.

I sat down in the stall, but something felt off. I glanced at the door, it was supposed to be locked, but it had opened just a crack.

And there she was. Yolanda’s eyes, sharp and suspicious, were peeking right through.

I nearly jumped. "Yolanda! What are you doing?"

She pushed the door open a bit more. "It wasn’t shut properly. I was worried something might’ve happened to you."

"I’m literally just using the toilet. What could possibly happen? Can you close the door, please? It’s weird having someone stare at me," I asked.

But instead of stepping back, she leaned half her body into the stall. "Trixie, you’re not… on your period, are you?"

I kept my cool. "I haven’t had it in almost eight months. Didn’t we agree to go for a check-up after finals?"
