What happens when you stop taking the pill?

I know obviously you can get pregnant... but what I'm curious about is the symptoms that are suppressed when it comes to AF. The biggest reason why I got on bc pill was because AF used to make me dizzy, super heavy, awful cramps, and made me frequently throw up! Since I've been on the pill all those symptoms have gone and its superrr light! Im currently still taking the pill and not any time soon going to get off of it... but im curious. When I want to start trying for kids and get off of it, will all those symptoms come back?
