Long term effects?

Clover • Caribbean girl 🌴
Hey everyone. I'm 20 years old and a university student. My period is never on time and always comes with the worst cramps before and during it. I was told birth control could lessen my cramps and make my period regular and I'm really interested in it. But my boyfriend and I are concerned about any long term effects there might be in regards to getting pregnant later on.  Can anyone give me some insight please? Thanks 🙂
