It is very confusing, try not to strees yet (i know i know...easy to say =P) I was on the pill for about 6 or so years, with like a couple of month break in there somewhere. I had no idea what my cycles were before hand.. but for the 2 years my cycles were crazy, long and irregulare (between 32-40 days). It was literly right on the 2 year mark they started becoming regular and now are about 30-32 days.
everyone is different!! but thats just my experience.

ps. welcome to BB and the crazy insane world of TTC =)
