Should I go off the pill?

So I've been on BC since fall 2013. I was put on it mostly because my periods were irregular and uncomfortable. I'm 22 currently and I've heard you're not supposed to be on the pill for more than 2 years.. Is that true? I do want to go off of it to see how my body naturally feels again because it's been a while. I'm not planning on having children yet. I have a appt. in early June for a well-adult exam,but I didn't tell them about my BC question, can I just bring it up while I'm at the appt? I have anxiety and this makes me nervous for some reason
