A little girl advice

Hey ladies! So I have been thinking a lot about possibly taking birth control. I don't have any reason for it other than having horrible acne lately and having terrible cramps every month. Do you take birth control for these things? Does it help? If so, what kind do you use so I can ask my doctor about it? I'm pretty much just looking for any advice you have on the subject and whether or not it has worked for you. Thanks ladies!
