Yes, once you reach a certain age, there is a higher risk of having difficulties conceiving, miscarriage, and a child with DS or other problems. Being on the pill for so long can also make it hard to conceive once you do come off it, and the long term effects can really take hold of your cycles.
But it's your decision, not mine, your doctor or anyone else. If you don't feel ready for a child -then stay on birth control and when you are ready, then you'll just have to face whatever comes your way.
