Should I start the pill

I’m a 20 year old college student. I’m not fully sexual active in the sense that I haven’t had sex (penetration) but I do other activities 👀. The reason I want to start taking birth control is for my period, because it is sooooo painful sometimes I can’t even get out of bed no matter how much medication I take. My period is all over the palace always starting 4-6 days late each month so my period is one a different week each month. I don’t really understand what that means ? I’m also scared to take it because I have had acne in the past but it has gone away; I hear that some people when taking birth control makes it worse. Also the fact that some people say that it can be harder to get pregnant in the future. My mother had a hard time getting pregnant so I just don’t want to have that hard time when I try for children. What should I do ?
