Is this a good way to say it? Weirdest thing to steal

I'm not mad about this.

My sos teenage sister and brother came over while I was at work and hung out. She is 15.

They are totally welcome by me, to use anything they want. They have never stolen anything.

I have a dresser drawer that is packed full with pads/tampons/panty liners/pregnancy tests and my stock pile of birth control pills.

She knows where it is, I've told her she can take what she wants. I meant like period products if she started while at my house. I didn't think she would take this though.

She took a box of birth control pills. Like i figured it was obvious that like, I take those and need those so I don't create her niece or nephew. But no, she took em. I thought I lost my mind or something. I went to put more pads in there because I'm weird and like to have it perfect for my next period and I noticed I only had 1 pack left.

Its not a big deal, I'll just order more. Obviously she needs them and I am glad it wasn't a pregnancy test that she took. But she can't just take mine because I have a 3 months worth of a cycle of pills and I have to order another 3 packs. She took a packet that won't work like she'd have to be on the packet I'm on now for it to get into her system correctly and be effective.

She took next months pills. I typed out a message and I want to know If it's okay i guess.

"I noticed that you took a box of my birth control pills. No worries, I'm not mad at you. But I have it all set up to where I need those. Plus, you need to see a doctor before you start birth control. Just in case you have any kind of reaction to them, you'll have a doctor that can help you figure it out. That pack you took, I wouldn't trust it because you have to take this kind in a certain order for it to work. It's the kind where you get a period every 3 months.

I can help you get birth control if you're really needing it though, just come over and talk to me and we will figure it out. Have you talked to your dad about it? If not I can help with that too. There's nothing wrong with being safe"

She only lives with her dad. But I feel so weird about this 😥 I would like for her dad to know if I help her get on BC. She's a minor and I don't want to overstep my boundaries.
