Breaks from the pill?

Rosie
I've been on the pill since I was 15, and I am now 20. I was dianette first to regulate my periods, then my doctor changed me to logynon when I was about 17, and I've been on it ever since. 
Does anyone have any knowledge/experience about taking the pill for a long time? Should I give my body a break any time soon? I use the pill as my primary form of birth control so it would be kind of a hassle to come off of it, but at the same time I don't know if I should be on birth control for such a long time as I've heard it can be a fairly bad time when you come off it.
