At your clinic's website, there is Infertility Glossary. Under "contraceptives, oral," it states that "Up to 3 percent of women taking the pill will become anovulatory when they stop taking it." However, elsewhere on your site, the "Clues from your past page states: "Using the pill won't impair your fertility." Which is correct?

Both are correct. As many as 3 percent of women develop a menstrual irregularity (fertility problem) while taking the pill. For example, a woman may gain weight or develop other conditions that may interfere with fertility. Still, if there are no other reproductive health factors present, there is no evidence that the pill in itself will result in any fertility problem that would persist longer than six months after you stop taking it.

Also, because the pill induces regular cycles, it may mask an existing problem, which then becomes apparent when you stop the pill. Some of the factors that may disrupt the menstrual cycle include thyroid problems, pituitary problems, weight changes, stress, diet and exercise. Unfortunately, our tests will not always indicate the reason for a change in your periods. If you do not have a period within three to six months after you stop the pills, you should consult with your physician.
