P.A.
Happened to me when I first went off the pill. I didn't have a period for about eight months. I went through all kinds of infertility testing. Nothing was wrong, so the docs thought I was going through some sort of perimenopause even though I was only 30. I finally had a period, and I was about to start taking Clomid to get things going on the pregnancy side-but I didn't need it, because that was the last peiod I had until my son was born! :)
