S.
I was the same after being on the pill for only 2 years. I went off, hoping to get pregnant right away and I didn't get my first cycle until a year later and then it was only once. I then went another 6 months before another cycle and then 3 months before the next. I was also wondering if I had really messed myself up by being on the pill. I ended up pregnant almost 2 years to the day I went off of the pill. In that time I had a total of 4 cycles. I have never been regular again. My doctor just said that there was nothing wrong and that I just had to give my body time to to get rid of all the hormones and regulate itself. Be patient, it will come back.
good luck,
S. ( mom of 4)
