I did talk to my doctor about it a couple of years ago and she suggested taking myself off the pill for a few months to see what happens, but I was just about to get married so I didn't want to and I'm not sure how informative that would be anyway as my periods were always madly irregular (anything from a 2 week gap to a 3 month gap naturally).
But now I'm wondering. What would happen if I just kept on taking the pill?
