Concerned about the pill

Hi! Im 16 years old and not currently looking for birth control, but when the time comes around, I want to know what's right for me. A lot of my friends are on the pill, but I hear the pill alters your periods. I want my periods to stay exactly the same as they are now. Not getting rid of them or anything. I just dont like the idea of not having a period. So im curious, what birth control should I look into if i want my periods to remain on a regular cycle with no change? Im not good with shots or pills id have to remind myself to take everyday anyway.
