Birth Control Pills

Okay, so I'm 14 years old and I've been thinking about taking Birth control. At the moment, it's not because I'm having sex and don't want to get pregnant. That can wait. I really just wanna take it to make my periods more regular. I heard that it can also help with acne, but I could be wrong.

Is it okay to take these pills just for those reasons?

Also, what do I do if I have my period? Do I still take the pills while I'm on my period?

Next, how do I tell my mom if I want to take Birth control?

I mean, she shouldn't be worried about me wanting it for sex because my boyfriend lives in another state. But my mom can.. Overthink. She might still think I'm having sex.

My mom and I have talked about Birth control in the past and she even said that people take it to make their periods regular and all of that. She explained that she'd take me to get some even, just for period purposes and such. But even though she says this, I'm afraid she'll get the wrong idea and change her mind, not taking me to get any.

My mother and I haven't been on great terms these past two days either. So I'm even more worried.

Last, my boyfriend. My boyfriend seems easily jealous when I hang out with some people. He even asks me sometimes if I plan on cheating or breaking up with him. I don't want him to feel scared, and if I get these pills and take them... I'm afraid that he'll get the wrong message and be even more worried about me cheating and whatever.

How can I tell him that I'm not taking the pill because I'm having sex with other people?

Thank you so much for taking the time to read this through. I'd really appreciate some help with my questions.

And please, have a great day!
