Hi Starting Out,

I agree with Neatisme ... the pill doesn't cause cycle irregularities but it might disguise the cause until such time as you come off it and then you will become aware of the issue. Once you stop taking the pill, it is out of your body within just a few days.

It might be something really simple like one ovary not yet ovulating regularly but given your age, I would be going to a doctor and seeking advice should you be wishing to conceive.

I am 39. I used the pill on and off for many years, stopping it finally when I was 34. I had endometriosis which was hidden to a large extent by the pill usage. I did not conceive naturally and ended up using assisted conception when I was 37. Many people don't need AC but I think you at least need to have your cycle going regularly for the best chance.

Good luck with everything.
